Victron 90AH AGM on BlueSmart IP22 12/15/3

Hi All,

Unlike my previous charger (a Mastervolt) this slick Victron charger does not give me an option to select battery type (other than Li). I have two Victron AGM 90AH batteries and want to know if I should charge them 'Normal' or 'High' (or other??)

On this forum I read AGM doesn't like voltages over 14.4, on other fora I read they should be charged @ 14.7 V. Sadly there are no manuals around for these batteries. (at least not on the Victron site)


I bought the Victron charger under the assumption it would be a better match, but now I am not so certain.


So any help would be appreciated.

LiFePO4 regulator settings & 3 port BMS connections???

@Justin Cook - Bay Marine Supply USA


I am still waiting for anyone to confirm I am correct on the new battery presets (which I have been told don't exist), (see pics attached).

Or am I missing something?

I also have had no reply in about 6 weeks regarding confirmation of my BMS connections being correct or otherwise, I am not comfortable proceeding with the final connection of the BMV-712 to the battery positive until I receive same.

I have marked up a picture with labels for for all cables, hopefully that makes it clearer.

I actually just followed former advice to another person put the shunt in the Blue Bat Neg cable here: https://community.victronenergy.com/comments/22867/view.html

I also included a picture of the battery & BMS before any connections for clarification.

Stay safe folks.

MPPT Control scrolls "Fetching History" continuously

I have an MPPT 150/35 BlueSolar charge controller and a MPPT Control Unit v1.0 (SN:HQ1746JQ9M5). The MPPT Control continuously scrolls "Fetching History" and it can only be stopped by disconnecting the MPPT Control cable from the MPPT 150/35 charge controller. I have taken it to the Airstream dealer from whom I purchased it and they say all they can do is unplug and re-plug it to reset it. Otherwise, they insist that it is because I am pushing too many buttons (even when I have pushed no buttons at all). I am frustrated and would like to fix this problem. The MPPT Control software version is 20 50, the MPPT software version is 5 1. Can you help me with this problem?

Adapted plans supporting performance optimizers?

Dear Victron-Team,

PV module performance optimiser get more and more meaning in difficult environments, but also in terms of emergency shoutdown for all PV modules.

Since Tigo is supported in the meantime by a series of inverter manufactures (e.g. Fronius, SMA, Solax, Growatt, Omron, Kostal, Sungrow, Schneider Electric, etc.), I would appreciate, if you could consider the support with Victron MPPTs on near term.

Are there already any plans contrary to your statement from 2019?

Argofet and MPPT compatibility question

HI guys,

Can someone with expertise with the Argofet help me, I want to add an Argofet to split charge my VRSLA start battery and my LFP house bank. Easy so far. I want to connect an MPPT controller to the input of the FET and utilize the alternator energize circuit to tell the MPPT that there is voltage. The solar controller needs to see voltage at the battery terminals or it wont start charging.

This is what I had in mind, will it work?

[image]


The following is from Victron ArgoFet documentation...


Alternator energize input
Some alternators need DC voltage on the B+ output to start charging.
Obviously, DC will be present when the alternator is directly connected to
a battery. Inserting a Diode or FET splitter will however prevent any
return voltage/current from the batteries to the B+, and the alternator will
not start.
The new Argofet isolators have a special current limited energize input
that will power the B+ when the engine run/stop switch is closed.

Hi, my BMV712 starts off from 100% when I start up the inverter (Multiplus Compact 1600VA) but then slowly drains to 0% and never rises above it again. The MPPT however gets to float nicely every day and stays there. I have a refridegarator connected to the inverter so it does go on every now and then but still the MPPT stays on float.

Dunno what’s wrong. My BMV settings are as follows.

SmartSolar MPPT problem with Tigo optimizers?

Hi!


I have a strange problem with my Victron setup. First the setup: Two houses which I plan to take off grid on the countryside in Sweden. Both equipped with a Multiplus and a SmartSolar MPPT (250/100), then connected to a battery bank of regular led-acid 12V batteries. The solar array is equipped with 4 300W Solitek panels each with Tigos smart optimisers (TS4-L).

Now to my problem: During good sunlight the output is very “spikey”, meaning current and voltage goes from full to zero and sometimes the current spikes in VRM even shows up to 15kA (is this even possible??). Anyone with similar experiences with similar setups or any tips on how to get a more stable output?


See screenshots from VRM & VictronConnect (both at full sunlight on the panels).

My Victron app is showing my production at 1-2wh a day when it used to produce around 1.5kwh per day.

[image]

It’s summer time so I’ve been leaving my refrigerator running all day for the last couple months. I bought my truck into the shop for a check engine light but when I brought it back home the Victron app suddenly showed that instead of producing the normal 1.5kwh of power a day, it was only producing 1-2wh a day. Even with nothing running, I would typically produce 10-20 wh a day. After two weeks of having everything completely off, I broke out the multimeter and began reading everything. The Victron app is showing my charge as being in the float state but my multimeter is reading the batteries as only 12.2v with solar collecting 35-36 pv and sending 13.7v to the battery. i turned on the fridge to see what about my battery power and it dropped to 12.1v with the Victron box remaining in the float state. I then turned on the truck and began charging the batteries through the truck batteries and raised the batteries to read at 12.9v however with the fridge running, after about 30 minutes, the batteries were back down reading at 12.4v. Still the Victron box is indicating the float state of charge.

Has anyone else had this issue or can tell me if it is the batteries that need replacing (I have two 350amh batteries connected to be 700amh at 12v) or if the Victron box is the issue? Possibly the box thinking it is in float state means it is not delivering any voltage to the batteries so they are depleted. Or the batteries need to be replaced because they can’t hold a charge.

This all started when I dropped my truck off for a check engine light. I left it at the shop for 3 days during which time they may have had it inside and outside since it shows it made some solar those days. I’m worried maybe it was inside too long so the batteries might have died and now they don’t make their full potential anymore. Or possibly the shop flipped a switch or a wire they didn’t mean to touch. When I asked, they didn’t recall hitting anything unrelated to the check engine light but I wasn’t there so anything could have happened over the 3 days. The Batteries are expensive so I’m hoping to fix other things before replacing the batteries.

Victron & Helioscope

I've been working with the guys at Helioscope to try and improve their support for Victron products.


I need some help from team Victron to try and get this right.


I sent them the datasheets for the Multis and Quattros and asked for them to be added. They replied:

"Given the number of optimizer/inverter combinations it will take a long time for us to upload each combination."


I replied with:

"You will see that all of the MPPTs / Charge Controllers / Optimisers / DC - DC Converters / Whatever we want to call them have an efficiency of 98%.

So, with the exception of the EasySolars which have the MPPTs built in, I would create one profile for each MultiPlus and Quattro.

That should not be more than about 10-15 profiles.

But list them as follows:

MultiPlus II 5kVA (4000W) 48V via Victron MPPT (98%)

Then take the specific inverter efficiency, in this case 96% and times by the 98% and get 94.08% overall.

Another example:

MultiPlus II 3kVA (2400W) 48V via Victron MPPT (98%)

95% * 98% = 93.1% overall."


They responded:

"Yes, that is how we would handle the efficiency, but still given the large number, there end up being hundreds of combinations, so if you can give us the first handful to start with, we can begin there.

Also, does Victron have a version of their datasheet with 'average' efficiency? All I see listed here are "max" efficiency values, but that will not capture their performance over a day/year."


I believe in their first comment they have misunderstood my suggestion. I am suggesting that they add only as many devices as there are Multis or Quattros because the MPPT component can be assumed to be the same for each, regardless of model.


So, I have two questions:

1. Is my assumption that the efficiency of *any* Victron MPPT can be assumed using a constant against a pairing with any Multi or Quattro?

2. Can Victron answer to an "average efficiency" that we can use as this constant instead of the "max" figure in the documentation.

Prioritise PV from MPPT over Grid power

I have a Grid-Tied Quattro 48/15000 with 860 Ah of battery power with a usable 20 kWhr .

My maximum allowable grid usage is 5.5kW and I have a PV array of 36 panels with a peak output of 8KW.

There are two 18/250w MPPT’s attached that act as charge controllers and supply AC power when required.

It is setup as an ESS system with Self consumption (With Battery life) and DVCC disabled

The problem is that the system prioritises the Grid input over spare PV power. Therefore it is inefficient and I am paying for grid energy when spare energy is freely available from the PV/MPPT.

I am reducing grid power usage by modifying the 'Grid set point' in ESS depending on the weather and my energy requirements. Ie When I have a high demand, I set the grid to maximum and at night reduce this down to a much lower level.


Is there a way to instruct the system to use maximum PV output for AC and only use the grid to fill in any shortfalls?

The installers here in Spain do not have a lot of experience of these Victron systems and have not been that helpful in fixing these complex issues.

Does the MPPT have reverse current protection from the battery?

I'm looking at a description of the Cyrix Battery combiner and I would like to confirm if this device can be used for protecting the MPPT from reverse current from the battery.

MPPT data sheet does not explicitly mention reverse current protection from the battery side (but mentioned for the solar side). Does MPPT have its own internal reverse current protection or are diodes necessary to prevent damage from back current?

MPPT 75/15 no volts at Load, Yellow LED not on

I can't figure out what is wrong with our BlueSolar MPPT 75/15 charge controller. Ideas appreciated. Situation: The yellow LED charge indicator light isn't coming on at all, even though there is sun on the PV panels and the PV open circuit V is 19.45 V. When the PV panels are connected to the PV terminals on the controller, V across the PV terminals is 10.74 V, while V across the battery terminals (with the battery connected) is 10.87 V. The fuse is ok, and the green power light remains on. All wiring is correct polarity. The only load is low-power LED lights, 12V DC, totalling about 25W. The controller is about 4 years old. Load voltage is zero, but I think that's because the low voltage load disconnect jumper is set at 11.1 V.

Smart Solar 150/100 Not Operating at 100% capacity of solar panels

So I finally resolved my last issue with my Smart Solar displaying the correct battery voltage on the main screen but incorrect voltages in the history page.

The first day I ran the whole system (2x Smart Solar 150/100 MPPT, 1x Lynx shunt +power-in/distributor, 2x 12v multiplus 3000 in parallel, and 4x Battleborn Li-Ion batteries) it ran great. Each controller has 8x 100 watt renogy panels (2x set of 4 panels in series ~80v open voltage) per controller. The first day one controller peaked out at 880 watts (it was a very cold day so the panels were more efficient since its rated at 100 watts at 25C), the other controller peaked out at 840 watts. The next day my Cerbo GX and Touch display came in so I shut the system down, plugged in the VE.Can and VE.Bus to the respective units and made the minimum entries into the Cerbo to get it going (IE wifi set up, VRM set up, 400 Ah battery capacity). Ever since then the controller REFUSE to put out more than 75% of the panel rated power, regardless of how many panels I have connected to the controller and regardless of the series/parallel set up (IE 4x in series was putting out 300 watts, 6x in series was putting out about 450 watts, 8x in a 4:2 Series:parallel would put out about 600 watts) and BOTH controller do this.

This has been going on for a week and as more time goes on the VRM logging (every 1 minute) is showing more and more dips through the day even though it is almost always sunny out where I live.

I even shut the whole system down for a day and brought up the inverters and discharged the batteries to about 80% then turned the solar controllers back on, reset them to their defaults, reassigned the battery to Li-ion, and got exactly the same results.

I also don't think the cables running from the solar panels to the controllers are the issue. Each controller has 1 positive and 1 negative running to their own set of panels. Used 10 AWG wiring and the run is around 100 ft from panels to controller. The controller then has 2 AWG to connect to the lynx system and 4/0 for battery/inverter connections.

Does anyone know why when I plugged in my Cerbo GX that the system just basically stopped working at 100%?

Edit:added photos of the history display on both controllers the two lowest peak power days were cloudy but every other day was basically 100% sun.
