Reset the meter, put some water bottles (that won't explode from freezing) etc into the freezer so it's not just running empty, and let the freezer run for a few days with the meter running, that gives you a better idea of how much power it needs over time. Ideally you do this with any device you plan on running on battery+solar.0.45 is Amps, 0.62 is PF, 56.1 is VA. I put it back on house power last night, as the battery voltage dropped below 12, and I had read somewhere that was not good. Got the batteries on a charger. Also, the 1500 watt inverter alarms at 10.5 and shuts down at 10 Volts. Thats good, I guess, but if the batteries can be ruined below 12, that does not seem to be a good safety feature... Also, I saw, with interest, that Tesla is producing 420 Watt panels. Not sure if there is a proprietary controller, or if any would do. Any thoughts on that?
Let me be clear, though: you'll need some new equipment no matter what. 100W simply isn't enough.
