I have a cabin that is off the grid. I am planning on doing solar but not just now. I need the money to get the cabin ready to live in. My question is if I get a couple of batteries a inverter charger and a generator that is not of the inverter type will I be able to run the generator during the day to use the power to work on the cabin and at the same time charge the lithium ion batteries without damaging electronics on my grid. Thanks in advance.
