Fast shipping! I opened it and modifiied some parts. There are factory installed two 6AWG spagetti pasta between the external battery terminals and the mainboard DC terminals... I replaced it to 2x50mm2 welding cable, no heat, no loss under heavy load. The inbuilt DC breaker has problem too, the switch stuck in off position, I removed and disassembled it, i found a spring washer stucked in switch mechanism :D :D no comment.. I repaired and stored it for later use.__Good things: _1. very very effective big cooling fans on the top not at the bottom like other inverters_2. two small cooling fan for capacitor block and for the two big inductors very good!__Bad things:_1. PV, AC terminals on the board are slide-on connectors, for this power 6.2kW I think it is ehhhh...._2. NO AUTOMATIC PEN / NEUTRAL-GROUND BONDING RELAY its essential in EU. If you connect it to a TN-S network and externally make a NG bond the built-in RCD tripping or not functional__Overall its ok for the money, needs testing for final conclusion.

The most important thing is that it works! OK. It does everything it should do. When charging the batteries from the solar panels, the fans are buzzing at full speed. When drawing power from the batteries and converting it to 220V, it doesn't necessarily buzz, only at high energy consumption. In the battery settings, after switching to User, all parameters are ready for LiFePo4. So you don't have to do too much adjusting, only these fans are bothersome, especially since it works only indoors.

Najważniejsze ,że działa! OK. robi wszystko to co powinno robić. Przy ładowaniu baterii z paneli solarnych wentylatory szumią na pełnych obrotach. Przy pobieraniu prądu z baterii i przetwarzaniu na 220V nie koniecznie szumi, dopiero przy dużym poborze energii. W ustawieniach baterii po przełączeniu na User właściwie wszystkie parametry są gotowe na LiFePo4. Tak że nie trzeba zbyt dużo kombinować, tylko te wentylatory są uciążliwe, zwłaszcza, że praca tylko w pomieszczeniu.
