I'm looking for an inverter for my off grid cabin (mountains, cold) and have narrowed my choices to either the Solark 12k or Growatt SPF1200. Both are 240 volt split phase, which I need. After watching a very recent Signature Solar video, they emphasized not to use the inverter under 32 degrees F., which would be difficult in my situation (unheated shed, batteries will be heated). The Solark has an outdoor rated model that goes down to much lower (-13 F) ..
The growatt has much better specs in term of capacity and is half the price of the Solark, so it's tempting...
Has anyone one had experience with the Growwatt SPF1200T (48v DC/240 split phase AC) in unheated, COLD conditions?
Seems like so many solar folks and distributors live in warmer climes where this is not a consideration and don't have first have experience.
