Sorry, away from "technology" so just catching up.
So regarding the parallel, mine is definitely the parallel version it’s an SRNE inverter - though that info took some prying out of the reseller Sunboost (although as
@42OhmsPA and I had already noted in the manual they sent it even states on one of the pages SRNE). Anyway, I used the link I posted earlier originally to enquire about that inverter and asked if they could be paralleled. They told me, as
@Zwy has rightly pointed out, that that specific one cannot be - as it is the stand alone 10k, but Sula (the contact at Sunboost) said if I wanted it with the parallel function that was no problem they could send me the parallel version of the 10k instead. That’s indeed what they then sent. I hope that clarifies things?
Regarding warranties…..As Sunboost sell it as their "own" inverter they claim they warranty it - this is something I take with a pitch of salt. That is because so far in all my dealings with items direct from China (batteries, flail mower, mower gearbox, box blade ….swim spa!) warranty/guarantee, regardless of the company, it seems is just sales fluff. Any item I have had issues with (which has been few to be fare) and asked about warranty on so far the companies never seem to honour the warranty anyway…..or at least want you to buy something else and then they will send spare parts for your old purchase with your new purchase….
HTH
