Had some defective SPF5000ES units replaced with all new, due to internal shorting screws the manufacturer failed to remove. All fresh starting last week. 4 units in parallel. Have been operating one alone, each separately over the past week, they each run perfectly fine, and I've never overloaded one so far. 4 units is probably overkill, it seems, but that's fine, I like a reserve. But when I try and operate in parallel, despite confirming all wiring is correct, and settings on all 4 are identical, they'll start (any different pair, happens to all) for a few minutes, operate fine, share the load equally, then fault and shut off. Tried 5 or 6 times this past week. Generally a shutdown and restart singly will allow functionality alone again. This morning changed some settings due to some of the errors they've thrown on fault, and now got a 09 bus start failure on both, now they're both trash. Won't restart. Getting thoroughly pissed at this China trash. I made a huge mistake putting all my eggs in one basket, almost $4k spent on useless undependable garbage. Wife is sick and tired of the shutdowns, and my golden retrievers get nervous and bark to leave the house every time I go into that room.
I suspect there's a hardware fault in these units. I'm operating on a third unit presently, just fine, at about 30% load. I've never exceeded about 90% load as far as I'm aware, I can watch the output graphs on the ShineServer app (another piece of shit software that is more buggy than useful, always showing errant information-another discussion entirely).
Has anybody else had any luck at all getting these units to play nice together?
