The battery WR registers this and activates DC out and the power reduction of the PV to 1/3 power = 27. The voltage or current on the supply line of the NA protection breaks down. (How to do that exactly, I have to find out)Дue to the power failure, the two contactors open from the NA protection

The network is disconnected by a large contactor. Red are the actions in case of power failure: PV and battery can be switched off by NA if malfunctioning.

In normal operation, the solar system feeds the battery charger and the battery is charged.ДЄt night, the battery is discharged via the same path. Except for the part with the Ouattro Inverters, I have already realized everything: Thanks in advance for helping me out! southwick asked at 11:51 AM The battery is hard to reach and it is only about a max of 4 or 5 weeks that we do not use our campervan.

Does keeping the battery connected to the main charger for longer periods have impact on the life time of a Lifepo4 battery and, if so, how big is this effect?Дisconnecting and removing the battery is not a realistic option.

(used to charge the batteries with the excess energy from the panels or to feed the sub-panel from the batteries stored energy). Under this scheme if one module is shaded, then the whole string is impacted.

Is it OK if an already fully charged battery keeps connected to the main charger by temperatures below zero degrees? Consider an inverter per string of panels or Consider a single central inverter for the whole system.

It is clear that the battery should not be charged below zero (better five) degrees. The questions are about what to do in a situation in which our campervan stands on a indoor parking lot with temperatures that may be lower than zero degrees. I do, however, still have a number of question to which I so far get only vague and contradictory answers.

I intend to install in my campervan the following setup: I am not entirely sure I understand what is accomplished when the BMV performs a 'sync', is this something that needs to happen regularly, or as long as the initial calibration is done correctly, will I be okay with a 90% SOC charge ceiling? The BMS modules will not have an issue balancing the cells in this scenario, and have been operating with 4.15v/cell max just fine so far. Ideally, I would kind of like the BMV to read the realistic SOC, being around 90% at this level, without having to reach the fully charged voltage of 29.4v, which would then mean, as i understand it, that the BMV would never synchronize itself.Д¬an anyone provide insight as to how I should best set the BMV to accomplish this, or if I even should considering it would never reach 100% soc reading in that case.

Right now, I have my BMV set so that it thinks it's full (and I presume then does a sync) at a charged voltage of 4.14/cell (x7= 29v (rounded up)). I have a Lithium NMC chemistry battery which is typically considered 'full' at 4.2v/cell, I've configured my charging settings so that is goes into absorption at around 4.15v/cell, which is maybe a tad more than 90% full.
