Since installing my PV system this summer I have been starting to pay a lot more attention to solar conditions, overall. needless to say, for the past almost 3 weeks now... my 2kw array has produced between ZERO and 0.8kw a day.
the cloud cover has been so thick that at peak production, I'm only getting 100-150watts. less than 10% production.
I would have to run my genset a LOT during December and January should I ever have a grid-down situation.
so, for anyone in Michigan considering a DIY off-grid/battery-based system... grid-assist for charging batteries is absolutely CRUCIAL. I have been importing the 3-4kw a day to keep my batteries charged appropriately. make sure you have a generator for backup charging and know how to connect it safely.
