Hi Folks!
I picked up 23 Trina 230 Watt solar panels and plan to install 20-22 of them to
power our 230 VAC well pump, the ham shack and in emergencies, the freezers and
refrigerators.
These are 29 VDC panels are ideal for ground or rooftop mounting. I would like
to run 48 VDC from the solar array to an adjacent ventilated shed where I can
place batteries and convert it to 230 VAC for the nearby well. I can also
split that into two 115 VAC legs from a breaker panel to feed the freezers and
refrigerators when needed. I'll also run a 230 VAC line to the ham shack and
use a manual transfer switch. The ham shack already has a small 14.2 VDC
LiFePO4 battery array and charger for the DC gear in the shack. The only thing
in the shack that doesn't run on this voltage are the high power amplifiers,
the air conditioner and some of the lights. We can live with 100 W radios if
needed, but if the 230 VAC feed from the solar array and its batteries and
inverter are capable, then I might be able to run the AC or the amplifier. We
don't need heat, as the ham shack is insulated and the gear keeps it snug!
Noise suppression is my first consideration for the system, so what are my
options for a solar charge controller/charger combo or separate units?
I'm prepared to configure the system in the shed for a 48 VDC battery array
near the solar panels, but it needs to put out 230 VAC. I KNOW that the next
question will be how big is the well pump? I don't know, but it has enough
power to lift water 140 feet.
Thoughts?
