HowTo PV Charger priority over Quattro Charger

A non-ESS hybrid connected to the grid with Quattro mode "on" will throttle down the PV charger and charge the battery from grid...


when, by putting the Quattros into "inverter only" mode, the PV charger could actually deliver the charge. Or at least any charge so it would not be needed from grid:


Obviously, the question is how to achieve PV charger priority over Quattro charger priority, so one could leave the grid on, but not at the expense of PV chargers being turned down, which IMHO should have been the default in the limbic (non-assistant) system of Victron devices anyway.

MPPT Bluesolar 150/85 no charge current incorrect display

Good afternoon

My Bluesolar MPPT 150/85 ceased correct operation after a small short on the pv side (unfortunately between PV panel fuses and MPPT )

First it showed a warning "inf 21 " then after complete discconnecting no more error messages but now

- current reading is 0 A , but PV current seems to be simply passed through

- measured current from PV is 7 amps ( cloudy ) and output current is exactly identical

- Voltage on panel is battery voltage + approx 0,7 V

- No MPPT function -

Is there anthing likee a fuse or so ?

Anything I can do ?

MultiPlus 12v/3000va/120amp doesn't seem to charge batteries.


Hi - new installation on our boat, MultiPlus system with 4x 200AH Victron LiFePO4 batteries. When connected to main power to charge (ain charge only mode) Mains and Buls LED illuminate, absorption and float flash, system kicks in, fan rush etc. After about 1/2 hr bulk LED goes off, absorption and float flash, fan off, mains stays on. However, the charge read out for the batteries shows no increase in charge. Have charged for a total of 3 hrs over the last 2 days (only 3 small LED lights and a floor water pump connected to system) and charge just continues to slowly drop as if it is not being charged at all... currently at 40%. Thanks.

Could my charger be faulty...?

Hi all. Just trying to understand what has gone wrong in my van power setup. I am using a Smart Blue ip67 12/13 charger with a 12v leisure battery to charge and act as a power supply which has been fine up until now. Charged the battery and ran my fridge on it fine a few days ago, but now that I am on a campsite with a 240v hookup connected, the battery has discharged to 11.9v before I noticed, meaning the charger is not supplying anything. The charger was also saying it was in storage mode for a day which I now know meant it was 24 hours discharging before that kicked in... Assuming my conncections are all good, why would the charger not be charging the battery or even supplying any power? The app is telling me now that it is on absorption charge at 14.47v but with 0.0 current and my battery monitor shows the battery is discharging, not charging. The charger clearly thinks it's doing something but obviously isn't. Is it faulty or am I missing something?

Mppt 100/20. Not registering solar.

I'm trying connect my 260ah AGM battery and 320w solar panel to my mppt 100/20. It registers the battery but I have 0w and 0v from the solar. I've triple checked the wires are connected properly and the right way round. I've checked the fuse and I've checked the wiring using a multi meter and there is power coming from the panel but the controller still isn't recognising it.

I'm aware it needs +5v above battery voltage to charge but I'd have through midday on a sunny day it would produce that easily.

What am I doing wrong? Anyone got any thing else I can try?

AGM Super Cycle Four Bank Significant Reduced Capacity

I installed 4 x 145ah Super Cycle AGM's 18 months ago (Still under Warranty). They were marvelous giving us days service before needing charge. Usual discharge to 12 volts.

This week suddenly we have extremely low capacity and using our normal charge methods (Sterling shorepower 40A charger set to AGM) or the boat engine alternator. Absorption charging at 14.6V and 14.4V respectively. The shorepower drops to 13.6V for float.

I only seem to be able to get 50ah storage into batteries (using NASA Marine Clipper BM2 battery monitor) and then the charge current is down to 1 or 2 Amps within 4 hours or so.

Why would this have happened to four new batteries and so suddenly?

Why would SmartSolar show just 2W in full sun?

I have a SmartSolar MPPT 150/60 with 640W of solar panels.

What does it mean that "solar" is just 2W in full sun? I am connected to shore power, so a separate charger is charging the batteries. Does the "2W" mean the batteries are just full and the solar.

Also, over the past week most days show exactly 80Wh yield each day, with Pmax 60-70W. It just seems to me something is off or has failed.

Blue Smart Charger & LiFePO4 Battery Smart not fully charging

Hi there :)

I have recently bought a LiFePO4 12,8v Battery Smart 200ah
It is not yet hooked up to a system as the facility is still under construction

The manual for the bettery says it must be regularly (at least once every month) charged to 14V (max 14,4V)

I have a Blue Smart IP22(1) 12|30 Charger

I am using the Victron Connect app to monitor the voltage of the battery
I have tried charging it twice and am now trying a third time.

The battery was sitting at 13.25V
Cell 1: 3.32V
Cell 2: 3.31V
Cell 3: 3.31V
Cell 4: 3.31V

When I start charging, the charger jumps straight to ABS
The battery voltage occasionally jumps to 13.26V momentarily
With Cell 2 jumping up to 3.32V momentarily and back to 3.31V

After an hour or so the charger has progressed to Storage
The battery voltage is still at 13.25V

Does anyone know why it is not charging up to 14V ?

Thanks very much in advance

SmartSolar 150/35 Stopped providing Watts out. Voltage sufficient from PV Panels. Please help.


As title states I have a Smart Solar MPPT 150/35 hooked up to charge my battery bank. I have made no changes to the system in months, and I used to be able to pull about 1.2 KWH daily. It now will not output any amperage to charge my batteries.

I fear that the internal fuse is blown. Currently the PV Panels are producing around 35-45V. Which is sufficient to charge to my 24V battery bank. The rig(sprinter Van) has not moved at all, and the 'Charger Enabled' slider is activated in the Victron Connect app. How can I tell if the internal fuse is blown or not?

Things I have tried so far:

Disconnected the VE.Direct cable and 'forgot' it in app then reconnected/added it back.

Verified settings are correct for charging.

Checked the fuse to the batteries from the MPPT Charge controller and it is good. There is continuity from battery to charge controller.

It's hot outside so I checked the temperature around Charge controller and controller itself and nothing is above 100 degF.

The LEDs on the unit are blinking 'FLOAT'. According to the manual this means that the 'Charger Temperature too high'. However in the manual it also states that the full output current up to 40 degC (104 degF). I am not exceeding the specs of the unit, I checked with a recently calibrated infrared thermometer all around the unit(heatsink fins/cables in and out/body of unit in all corners and center). Also, when it's early in the morning in the van and it was like 75 deg F inside the van, it was not working then either with full sun and voltage from PV panels.

Also it should be noted that this is installed in a van conversion, so it's not going to get cooler in the van, it will always be hot when the doors/windows are closed and it's summer.

How do I test the internal fuse of the charge controller without removing it? I bought it in September of 2019 and it had been working from October until about ~May 15th. I'm just about to take my van on a trip and I need this fixed asap.

Suddenly MPPT 100/30 sending PV voltage to battery but no current

I set up a 12v system in a camper van over a year and a half ago with a 175w solar panel, SmartSolar MPPT 100/30 controller, BMV-712, and a 50ah Battleborn. Ran great with no problems. Two months ago I added another 50ah battery in parallel, ran great with no problems. It has been very hot recently and temps have been getting over 120 F in the van when parked. I started to notice that my vent fan was beeping, but didn't think much of it until my fridge had completely shut off but my lights still worked. I then noticed that the charge history showed my battery's voltage maxing out at over 20v for a week and that that no watts from solar charging were recorded for the previous 5 days.

My charge controller just keeps showing the flashing bulk light indicating "no charge". Even in full sunlight with my panel's vmax coming through, but no current or power according to the charge controller app. Strange thing is that the unregulated panel voltage seems to be making it past the charge controller. If disconnect the panels and charge controller, the battery voltage will eventually stabilize. I am assuming the BMS on my batteries has kicked in to stop charging, but my loads must have been getting the PV voltage direct. Hence the fan beeping and turned off fridge.

Other weird part it that in direct sunlight, my battery monitor will register watts coming in but the charge controller wont and maintains the flashing bulk light. In full sunlight, the BMV will record 21v. I have a breaker between PV panels - charge controller and charge controller - positive bus bar. Testing voltage on both sides of breakers and they seem to be functioning properly. Not sure if high temps could have done this, but my system has functioned without issue for a while prior to this.

Any help would be appreciated.

Umpp = 33.16V Uo= 40.53V Icc= 9.98A

The Modules are connected in series so:

U_PV_IN = 81.06V I_PV_IN= 9.98A

Batteries: 2x AGM 12V/220Ah (100h) in series

The temperature sensor is connected on the minus pole of the batteries.

If the Inverter switch is on the inverter work fine but if I switch it to charger position the absorption and the Float leds start blinking.

No inverter or Battery Charging. Digital Multi Control reads Absorption
I got four 8DL LifeLine batteries and a Lifeline Starter Battery, a Victron Digital Multi Control PanelVictron BMV-712, Victron Color Control Display, Victron Multi-Plus 12/3000/120-50 120V, Balmer Charger Regulator and Duo Charger for use with the engine on.
While at the Dock and Plugged in to Shore power. I learned that i had a Battery Monitor and this was where i could reset History. As i had very low and High voltage history from during install. So i wanted to reset these. Found in the manual how this was done. I also learned that i could connect to the BMV with Bluetooth and the Victron connect app. I connected and saw i had my battery capacity set to 620ah when total i had 1020ah. I corrected the Battery capacity to 1020ah. Other then that i made no other changes to the system and only reset the history. Which is item 63 in the select menu of the BMV. I also had the inverter set to on but the Digital Multi Control panel automatically switchs to chargeing when AC is available from either shore or genset which it did. I was on shore power for about Three weeks during this time before noticing the issues.
Currently at anchor with no inverter useage or main Battery Bank Charging. Because i am getting battery low voltage/power warnings on both the Color Control Panel and Digital Mulit Control panel; so no inverter. With the generator on i get no voltage increases to the Main Battery Bank and if charging. Then its not putting enough into the main battery bank to off set onboard useage. The Digital Multi control reads Absorption as does the Color control panel. But its only charging the Starter Battery. If any is going to the main battery bank its very low current/voltage. If i shut off the generator i get a Low Voltage/Power warning on the color control panel. With a warning that varies depending on how fast it reads. Stating 14.42V as this was the voltage just before it cuts out from charging the starter battery. The BMV and Color Control Panel and a MultMeter read 98% 12.82V -5.2A from the Main Battery Bank. If i set the Aux input ,in misc, to Starter Battery on the BMV it reads 0.03V. Prior to useing the Victron Connect app. I wasn't finding readings for the starter battery and it wasn't apparent to me where and if it was being monitored. But have never had issues with Charging either one before.
I motored about 6hrs. During that time the Balmar charger regulator and I guess the duo charger functioned to charge the main battery bank and the starter battery.
I am showing low power on the color control panel and on the Digital Mulit Control panel. Off and on, on a cycle, On the Color Control Panel for the inverter/charger Multi Plus.

At this point I have reset the dip switchs on the Multi plus charger inverter to settings that are more in line with whats in service. Did this the best I could with the available infomation. In the hopes that resetting or inputing the operating parameters would possibly clear up the issue. It hasn't accomplished that. As i am at anchor and the inverter trips off when under load showing low battery light on the digital multi control panel. But volts are nominal at 12.8v. Possibly because i reset the dip switchs. I had use of the generator to charge the main battery bank once. When i ran a coffee maker or microwave the inverter cuts out and the digital Multi Control Panel. Shuts off too. This also caused the battery charging from a genset that was finailly going to the main battery bank to as yet no longer occure. Even after resetting the dip switchs.

At this point I possibly I have a Multi Plus inverter/charger issue. That is preventing operation of appliances due to a incorrect or a corrupted setting. I've checked what fuses I could locate and they're intact. It also should be noted that before when the inverter was under load. Say anything above 20amps. Like when i run appliances. A fan would come on within the Mult-Plus to cool down internal workings. This no longer occurs.

I plan to use a MK3-USB to set operatin perameters useing a laptop. In the hopes that the Dip switch weren't correcting the issues. Weren't being inputted or saved correctly or that i can get the fan to function.

I wonder if there are a whole list of settings that got negated from what they were before i connected with Victron Connect app. As these values seem like default parameters. Or if resetting the history may have caused a issue. It also seems that the main battery bank while being displayed on the Color Control panel and BMV. Is being read by the Digital Multi Control which sets charges and does inverter function.

Hi, I have a multi plus installation in a narrow boat charging 4 sealed lead acid domestic batteries, I’ve noticed that the unit is not displaying any charging indicator leds when connected to the shore line in both ‘on’ and ‘charger only’ modes. It has worked in the past at this marina. I’ve followed the trouble shooting in the manual, reset the thermal trip, mega fuse is ok, swapped my shoreline supply to a different source. Next step would seem to be changing the dynamic and weak Ac settings using a laptop. Before I try this, is there something obvious I’ve missed / not thought of as it’s worked in the past. There’s no error lights present and when the unit is selected to ‘charge only’ it appears to self test, all lights flash once, then the green ‘mains on’ light flashes 11 times. On the 11th flash the ‘float’ light illuminates as well for a split second before both then extinguish. The inverter light then illuminates for a second and then extinguishes as the ‘mains on’ led illuminates steady - with no charging indication leds.
