Hello everyone,
I want to check my numbers and wiring size please. This is an off-grid build.
I have four PV panels -
365 Watts
VOC 40.8 V
Isc 11.33A
Vmax 34.00 V
Imax 10.74A
2S 2P = 81.6 V and 22.66 amps
I could run 8 AWG and put a 60 amp fuse, right?
I should run 6 AWG and put a 80 amp...
I’ve been running this for almost a year now. This November is started surging and killing batteries at night.
It seems like the inverter is restarting and drawing a surge and using batteries.
I have it set to use solar then battery and then cutover to grid.
Only charge batteries on solar...
There is no real difference here right?
It will be easier to wire my panels 2P2S than 2S2P.
So I’m planning to do 2P2S.
Or is it a problem for the diodes In the panels?
Thanks
Nick
I am looking to build something like the https://www.mobile-solarpower.com/2000-watt-24v-solar-system.html
I don't have a need for a 24 to 12 volt appliances.
I plan to build this for off-grid, in case power goes down and to use it occasionally for fair weather outside use.
Are my numbers...
I am trying to figure out these batteries specs and how to set my Growatt 3000LVM at 24 volts.
Using two batteries in series on my DIY solar.
Hello everyone,
I found these are sealed AGMs, 6 cell.
low float charge = 2.25 vpc
high float charge = 2.3 vpc
low equalize charge = 2.35 vpc
high...
