Re: PIP-4048MS inverter

Going further with burned inverters. Maybe it will be interesting for someone. 1) Capacitors "success". Tried to measure ESR by audio card at 16MHz and it's about 10-20mOhm. I think this capacitors are good but I can't find a place in the internet where to buy them. 2) Tried to measure optocouplers ...

Re: PIP-4048MS inverter

Good to hear that there are other repairers out there. There is such a throw away mentality these days, perhaps more so in the West. I think that it is all over the World tendention. I would have thought that too many panels would not be such a serious problem. But I suppose the control system has ...

Re: PIP-4048MS inverter

Hi, coulomb. 100 A is quite light for two inverters in parallel. It also sounds like they were only AC rated; you need DC rated fuses or breakers there. When they opened at something over their rated current, they may well have arced, pitting the contacts, and that may have interrupted the power to ...

Re: PIP-4048MS inverter

Hi guys! Sorry for my bad English, it's not my native language. I'm trying to repair a pair of 5kVa inverters. They worked in parallel and died in one time. And I want to guess why that happened. There was an 100A circuit breaker (C100 for 220V AC) between batteries and inverters (1 circuit breaker ...
