Pool Pump Faulting - EG4 6000EX

[lboucher26]

Last 7 days would be very bad example. Been very cloudy. On good days, i'm loosing about 3kw of sunlight because batteries hit 100%soc.
I generally have enough load that if i end the day at 100% SOC, I draw down to around 20% in the am.

I wouldn't mind using Solar Assistant to switch between SBU and SUB... ITs just that when i do, the pool pump faults... Which makes pool green, and wife not happy....

Have you checked what the voltage is at the pool pump when it’s running? If it’s already low then a switch over might trigger a fault.

My whole goal is to use as much solar as possible and not use grid. But if there is no solar and battery drained use grid. I don't really ever want to charge batteries from grid. That just seems inefficient and un needed use of the batteries in my case. So I set it to charge as slow as possible.

I was using eg4 mode set to state of charge 20% But for whatever reason the inverter firmware let the voltage drop until batteries were dead even though it thought state of charge was 20%. Use mode has seemed more reliable and with a setting 20 of 51volts it tends to maintain a min of 17%

What settings do u suggest?

Get rid of EG4 Mode....it is nothing but trouble....go to USE and set voltage parameters yourself.

I'm curious as well.
Was the wire gauge and run mentioned?

Well, so i am now pretty sure the pool pump only faults on changover from SBU to SUB.... Just not every single time?
In any case


Settings below seem to be working. It does however seem annoying that with the min 2 amp charge from grid. Overnight or in low light. Basically the batteries slowly charge from 17% to 20% and repeat over and over. Seems like unnecessary mileage on batteries, but maybe its such a low C rate its irrelevant...

Would be awesome if SBU to SUB just worked... OR if there was a slower charge rate..

Have already done.

Have not. Its less than 100', 12 gauge. So i doubt its a problem, but will check.
