A 120 amp alternator is delivering around 80 amps at idle speed. When all vehicle 12 volt systems are loading the alternator, cooling fans, lights, perhaps 30 to 40 amps are needed. The Victron Orion 12 12 30 is not very efficient, typically taking 35 amps from the alternator. It also runs...

No, can you identify which batteries need this? I guess it's a limited low current stage at absorbtion volts.

The DC input on the powerstation is used for DC power or solar panel, 11 to 28 volts, 120 watts, 10 amps. Connect your panel directly not via a external controller. The unit has an internal controller that accepts panel directly.

There is a tollerence on the panel specification, your new panels are generating a higher Voc. From the Epever manual for the 60A 150 volt unit,

Eight 108Ah batteries in parallel idealy need a higher charging current than the maximum of 20 A via the PWM controller. The generator at 60 amps is better and may be needed to bring the batteries to full absorbtion state. There could be issues with the batteries not being fully charged thus...

This may happen with low cost PWM controllers like the unit provided with your kit. More advanced controllers are usually protected against panel disconnect. In fact the Victron range of controllers happily operate without battery connection. ( once initially powered with a battery to...

Usually AGM needs a higher charge voltage than GEL , default for the 3210 on the GEL setting is 14.2 boost volts. Either change to USER and set a 14.6 boost volts or change back to sealed settings. Check load output is switched on, manual page 19,20. Possible faulty interconnection...

If a single battery charging limit is 10 amps, then with a series setup it's still 10 amps, that's the current through each battery. 10 amps seems low for a 100Ah battery, is this the BMS limit, or a recomendation? Charging voltage may be too high for new batteries, suggest 56.8 or 56.0 if...

Use a battery charger connected to the battery. The Meanwell type of power supply do not have an ideal current limit, they fold back or burn out if overloaded. Connecting to the MPPT input via a diode, (only needed in the positive path of each source), may work, ( use a 35A bridge rectifier...

https://www.ebay.com/itm/175874775173 https://www.ebay.com/itm/235361478930 Over time the batteries may/will become out of balance with each other leading to charging or power delivery issues. Since you will be using a 24 volt charger it's possible the weaker battery will hit cell overvolts...

Not serious but may prevent the battery pair from reaching the same state of charge. What is happening is that, under charge, one cell is reaching protection voltage limit and preventing further charging. The battery will still function under load. This is common with new batteries and it...

Hi, as sugested your batteries are overheating during discharge. There appears to be only one temperature reported by the BMS and this is the temperature of the battery cells or the temperature of the internal battery control electrics. It may be under high power requirements, the control...

The controller should charge to a target voltage, boost volts, ( absorbtion voltage), then after a period at constant voltage drop to float volts. The concern discussed in the video is that the controller does not drop to the lower float, but continuously charges at the higher boost volts. This...

No, the monitor does not need to know battery type, it just measures volts and amps, does some sums and estimates SOC. Both the Aili and the BMS will have errors, especially if low currents are involved.

No, I was discussing the boost duration, this is the absorbtion period where charge voltage is constant at boost 'target' volts. With a low charge current and a large battery this time duration can be zero or a short time, say 30 minutes. Some SRNE solar chargers get confused if the boost...
