Ever consider getting a UPS?
;-)
Actually, one more solar panel and I will have a separate 48v battery stack to serve as the storage cells for a UPS on this computer. It will then take over automatically when the genny is stopped. I have tried three UPS brands, but none "liked" the inverter output. More accurately, the inverter did not like driving the high surge current of the UPS, in essence an inverter driving another inverter...
So at the moment, a changeover relay works 99% of the time!
If you have frequent need for ups, or running the computer from batteries, a better solution is to drive the PC power supply directly from batteries instead of mains supplied by an inverter. There is one stage less, and you conserve battery power. I saw those PSUs years ago, but I haven't seen them recently :-? On the other hand, if you have -48 instead of +48 there are telephone exchange quality inverters that can be chained with no problem. I used them, but I suppose they are quite expensive (heavy duty and very reliable, 24*7). - -- Cheers, Carlos E.
