Hey forum, this situation seems a bit strange to me.
I just installed my inverter (Renogy R-INVT-PUH1-301235) and hooked it up to my lithium battery bank.
The lithium batteries are fully charged and currently outputting 14.19 volts. The solar panels are in direct sunlight and the MPPT charge controller is on float. I can see that there is only 1 watt currently coming off the solar charge controllers.
So I powered up the inverter and took a measure of its output voltage. Its bouncing between 290v and 300v AC. This cannot surely be normal?
I noticed that the inverter has a high level of parasitic draw (approx 1.5 watts). So I left it on overnight while the solar panels have no light so that the batteries drain a bit. I measured the voltage this morning and it read 238v AC coming off the inverter. Nice.
This is a problem though? I will be charging this battery bank from solar and also alternator so most of the time those batteries are going to be fully charged. Which means most of the time im going to be getting 300v AC to all my 240v sockets.
What are your thoughts? Is this a problem or is it normal? Has anyone else seen this before?
I don't want to fry my equipment...
