Hi All! I finally learned enough to flip the switch on my PowMr 5kw 48 volt hybrid all in one (120 v only) system which seems to only partly work so far - in that I can use the batteries to run my loads through the AC out (attached to a power-surge power bar thus far). But this all in one does not seem to see my solar panels and so my batteries are being used up but are not charging on this beautiful sunny day in Northern Ontario! Does anyone have any ideas? Are there any known problems with this inverter not recognizing the solar panels. I have read the manual about a 100 times while learning about electronics and electricity over the last 6 months. I am within the Voc range - happy in the center (of 450 or 500 vdc) around mid 300's using 9 X 230 watt panels @ 24 volts. My panels are all in series (fitting also in the happy center at 8 Amps or so of the 15 Amp limit). The picture of the solar panel does not light up on the panel and there are 0 volts displayed on the PV voltage in reading. I have the solar wires going into the top of a disconnect box that handles 30 amps. I have 2 X 15 volt (resettable) round fuses in this box, with the negative wire going through one of the 15 amp fuses and the positive wire going through the other 15 amp fuse. I think this may be an AC box instead of a DC box, but I am generally just using it as a "disconnect" as there is no need for fusing on this 8 amp solar input. And by the way, who the hell invented 'knock-outs', and what the hell have all the electricians in the world been doing for the last 30 years if NOT inventing a 'knock-out' to replace the current version of this brilliant solution that invariably makes a ragged, sharp and jagged edge of the box, and the nerves of the installer-seemingly perfected for the purpose of cutting through wires while apparently professing to be a reasonable solution to electrical box entry?
