My girlfriend is moving in, so electrical loads will increase. Getting an apartment sized heat pump dryer, small mini-split heat pump for backup space heating, small microwave, etc. So I need to double my array and battery bank, and am facing a number of decisions that I suspect many others, in one form or another, may be also be facing. So I would very much like to hear thoughts. I am totally open to suggestions, advice, and accusations of ignorance or stupidity. After all, that is why I am posting.
Here is my existing system:
*Two parallel strings of 3, 295 watt panels in series, for a 1.79 kW array with a Vmp of 135 volts
*Midnite Classic 200
*Four Rolls S530 6 volt batteries in a single, 24 volt string for 10kWh of storage (3kWh usable based on a 30% dod)
*24vdc loads: overhead light fixtures (led bulbs), ceiling fan, pressure pump, SunDanzer
