Just fitted a 12/1600 EasyPlus to my motorhome and I'm seeing some odd behaviour. Just wanted to get your opinion on it. The charger appears to take my battery pack to 14.6v on absorption, even though it's set to the default settings which should be 14.4. This is above what is recommended for my Victron Deep Cycle Gel batteries, so I'm worried I'm overcharging them.

I've connected the starter battery to the unit using the aux battery terminal inside the unit. This is supposed to be a 4a charger connection. When charging on main electricity the Venus GX is reporting that 120w is being sent to the DC system. If I disconnect the aux battery connection this current stops. This makes me think that it's pushing 10A to my aux battery not 4a. The aux battery voltage also seems to increase when the device is disconnected from mains electricity and I'm just getting power from my solar panels.

I've got a SmartSolar 100/50, Venux GX and BMV712 and 2 x 130ah Victron Gel Batteries.

I have a customer with a 3 month old Quattro 8000 and manual genset start. It was the first one I’ve ever installed

I have not been to site yet as it’s quite remote and quite a drive but thought id get some ideas before I go as there is no phone range on site

Customer has said that when genset is plugged in and turned on, the Quattro seems to not take the input and switches between charge and inverting every few minutes.

I have set the generator input current to 20A because of his existing cabling in the house which he wanted to leave but his genset is a Kabota 6kVa

Otherwise it operates normally without genset

I’m sure it’s something I don’t have set right in config but could I please get some ideas on what to change and look for.

Thanks

The CCGT do not range the percentage correctly to the voltage. It stays between 84 % to 100%. Causes low voltage shut down despite voltage 51 or higher. Quatro 5000 where ccgt sensor connected Quatro. Voltage shown correctly in CCGT. It is only the percentage not related to voltage. What can cause this disalignment?

That's probably more detail than anyone needs, but I'd rather get it all out there initially.

Short story: I'm trying to get the BMV's measured battery current to drive the Quattro's charger current regulation. I have a large DC system, which can draw more than the batteries' rated charging current, so the Quattro's own DC output metering isn't appropriate.

Long story: I'm not running on battery for very long, just minutes between killing shore power and switching to engine/generator power, so I don't need a huge battery bank. The 4 batteries here barely fit anyway. The Power-Sonic datasheet says up to C/5 (20A per battery, 80A for the bank) is acceptable. Still, 80A is way lower than the DC system, which can draw over 100A when everything's active.

I have a CCGX, which talks to the BMV and SmartSolar over ve.direct and the Quattro over ve.bus. It seems to understand the SOC from the BMV, and it does the math to figure out how much "DC system" load there is, but I can't figure out how to feed this info back to the Quattro to actually control its DC charging output.

I'm totally fine with short transients, like if the DC load goes away and 200A suddenly gets shoved into the batteries. They should be able handle that for a few seconds, just not hours at a time.

Is this what DVCC is meant for? Is there an assistant I should be using?

Thanks in advance for any hints!

for 24 v system 23.8 v limit of switch on grid power it is ok?

Does anyone have an efficiency curve for the MPPT in the SmartSolar Charge controllers? I need to know if there are any efficiency difference from 100W-400W range

Hi,

On a narrowboat with a well installed system by a top boat builder in 2006.

If I power off the inverter/charger, when I switch it back on, lights flash very quickly (on then off) but the remote panel's lights (2 x vertical rows) light up sequentially right to left and this process continues. I resolved this the first time with a good old fashioned heavy knock to the main unit and it worked but cpild of course have been coincidental. Then this happened again a couple of days ago (I'd isolated the power to get inside the unit to check for the temp. lead). Whether coincidence or not I don't know, but a few swift turns of the heavy isolation lever for the inverter/charger supply resolved this.

Does this sequential light display on the remote indicate a an insufficient power supply issue?

i need to ask about MTBF for CCGX firmware version 2.04, lithium- ion HE battery 24 /200Ah , cyric LI-CT 12/24-230 , lynx ion BMS 400 Amp

Hello,

I have an old Phoenix Inverter 12/2500, that has a very odd problem.

It reads the Battery Voltage wrong, and so it goes into Battery Protection Shutoff for no reason.

When connecting via VEConfig, the DC Voltage reading is drifting and jumping incomprehensible, but it is definitely not true.

It can take up to several hours for the Protection Shutoff to engage or sometimes it happens in minutes. The device comes back to operation after some time.

It is regardless if and how much load is connected.

It is also regardless if its hot or cold.

I tried to apply some light mechanical pressure on the circuit boards, too see if its a cold solder point or a hairline crack etc., but it does not affect the wrong readings.

I sent the device to Victron for repair, it did qualify for a send in, but there are no more spare parts available for this unit and so Victron was unable to repair. Maybe it would have saved me €100 for the transportation and check up fees, if Victron would have known this, before I sent the device to them. They offered, that i do not have to pay the fees, if they can keep the device. I was not very satisfied with the repair service, but thats not the point.

The Battery Protection Shutoff Feature could be easily replaced with a Battery Protect 200.

So is there any way to deactivate this internal Battery Protection Shutoff Feature completely?

or does somebody here know, where too look after on the circuit boards, to fix this?

It would break my heart to throw this device away...

Thanks,

Markus

I have a Victron MPPT 100/50. I have looked at Victron Connect and seen the various options to turn on & off including Streetlight setting.

What I wanted was to set a clock hour to turn on & off supply to the load.

I don't see any place to set that option, either in VictonConnnect or in MPPTPrefs

I also see that my device does not have separate load connectors, but understand that I can attach a relay and control it that way.

Is there such a setting? Or an ability to manually program it? The reason is that I want my system (a time-lapse camera) shut down at night and it does not have a self-timer.

If necessary, I am happy to buy a different Victron solar controller, as the 100/50 is larger than what I need.

Hi there,

I am attempting to remotely update the VE config in one of my systems, but the download process shows the error 1391 just after the page is automatically reloaded as shown below. Due to the fact that the downloading process takes longer than the usual time where the page is not being reloaded, it seems to be impossible to remotely update my system.

I have successfully downloaded other VE Configs on systems where the downloading process finished before the page was auto reloaded.

Any ideas how to solve this issue? Can I increase or disable the auto reload process of my VRM?

Good evening,

Unfortunately 1of the m8 circular connections from 1 of my 100amp batteries broke so I ordered a genuine victron replacement lead but the colour leads inside are different Colours.

I have removed an internal board to carry out a repair. Took photos of all connects only to have a phone issue. All is good except t for the four wires from the doughnuts, 2 black 2 grey. I numbered them 1 to 4 but did not correspondingly mark the spade connects on the circuit board. With no photo i am lost. I can see the spades they go to but there are five to choose from? Can't find a wiring diagram to follow.

Hi, I have an inverter/charger Multiplus 1200/230 installed in an off-grid solar system. When the battery voltage level goes low the AC output is sttoped and I have to turn off and on the inverter to get again AC output when battery is charged and voltage level is normal.

Is it posible to restart automatically the AC output when the battery voltage level reaches again the normal value? How?

Is it possible to change the battery voltage values to stop and restart AC output? How?

Thanks
