Well, the last 3 Sol-Arks that I have been involved on trying to get an RMA for, have literally taken 2-3 weeks just to get an RMA shipping label! (This was within the last month.)What complaints are you hearing?
I have only heard a couple and those typically involved people trying to do Gen shaving or something else that Sol-Ark told them it does not support.
All companies have unsatisfied customers, but let’s talk ratios on the forum since you mentioned it.
For every single Sol- Ark complaint how many signature solar complaints have there been?
So there is that.....
And things like external CT sensors being limited to far less than passthrough rating of the unit.... (100ish amps...) and Sol-Ark not lifting one pinky finger to help find alternative options....
And internal CT sensors backwards out of the box.... twice.... (btw, this causes all kinds of goofy readings and adverse actions from the inverter)
And randomly not charging until a complete power cycle was done on the units, despite the battery being very dead... like 46 volts dead.....
Or randomly limiting pv power despite not being anywhere close to the configured limits.....
I'll stop now, (there are plenty more random ones I could talk about) but I don't want to hear the "there are hardly any issue with Sol-Ark" thing.
To be fair, it seems like all of these newer Chinese made AIOs have their fair share of bugs, glitches, quality control failures, etc! I think it's high time to bring manufacturing back to the states! We are all too cheap (me included) to spend the extra money on U.S. made quality stuff, so we have sold out to overseas stuff..... just my 2 cents.
