Funny, I came away with a very different reading (possibly because I don’t need even 5kW and could easily get by with 3kW).
Lack of repair-ability may be an issue for a reseller like Midnight Solar but is a non-issue for me.
The fact that the specifications are for real and that the units can be pushed for 2+ years at close to max ratings is very comforting to confirm.
Fan wearout is related to fan usage and I’d be ready to gamble that at average power of 3% of max ratings with occasional short-term surges to 30% of max ratings, I’ll get much, much longer lifetime from the stock fans.
It would be nice if replacing a blown fan was doable but with any cheap Chinese kit, replacing the entire unit when it fails is a viable option.
Did you see anything that causes you concern this SRNE 10kW unit is likely to have problems an MPP Solar 6kW split-phase unit wound not?
