My power bill is mostly from my central HVAC. I want to run a mini split run from solar to offset my power bill. I am in South Florida and have 6 panes, totalling 1.5 KW ( of 33 volt solar panels. There are run as 3 units of 2 (66 volts each) to a 60 amp MPPT and about 5 deep cycle marine batteries. This system is not grid tied. The system seems happy but is only charging batteries which do nothing.
I get the batteries cheap from a friend (about $50 new).
I have a two low voltage cut off switches I could use: The Victron Battery Protect and I also have a battery isolator which will only lets electricity though when battery bank is over 13 volts. I could use these to either only allow electricity from the batteries to the inverter when the solar is charging the batteries or when the batteries are at least half full.
I don't want to assume I have enough batteries to last the whole night running a mini split. I don't mind if the mini split turns off a few hours at night.
- I don't want the mini split do be damaged by the power being shut off at night.
- I don't want to have to mess with turning the inverter or AC back on daily.
I'm looking at buying this mini split:
And this inverter:
Q: Will the mini split be damaged by the nightly power shut off?
Q: Will I this system be automatic, or will I have to reset or push buttons every morning with the inverter is given power through the low voltage switch?
Thank you very much.
