"Here - Hold my Beer"
I sort of asked this question a few days ago and got a couple of good answers ... but thought I would re-word it and see if I get anything different ...
So my company has donated (10) 445W solar panels and a battery to power a mobile aide station for one of the counties we work in. These were extra panels and batteries they had. The issue is that corporate thought we could just use one of the ALL-n-ones that they also sent (MPP 2424) that could only handle 5 panels if that ....
Along with the (10) panels they have provided a 24V 540Ah battery. ((YES its the damn 24V battery that is causing us all these issues - if it was 48 this would have taken 5 minutes)) but I digress....
Below is the specifications of those panels.
MAXIMUM POWER 445W
VMP 41.19
IMP 10.81
They need to power one 115V 8A circuit 24/7/365.
They would also like to every now and then charge a laptop or something BUT not exceed 7A.
SO worse case scenario - 5% of the time - it would have a TOTAL MAXIMUM USEAGE OF 15 AMPS but 95% (if not more) of the time it will only be 7A...
I wanted to find a simply all in one that I could just slap in a box - HOOK UP THE PANELS AND BATTERY ... high five my partner - and then head back to the shop to watch NETFLIX ...
BUT NOT SO LUCKY ...
There is NOT an ALL-n-1 that's out there that we can afford to also give away ... and I mean most of the ones that can handle that much energy starts running $$$$$ ...
My Plan B is to tell my guys just to get some EPEVER 80A MPPT SCC and connect 5 panels to the left one ... 5 panels to the right one ... run them both to the battery ... and from the battery get a good 3KW inverter AND WE ARE DONE ...
But just to make sure that I am not just being lazy ... I was just wondering if anyone had a Plan C that we could use to accomplish the above and try to keep the equipment (the SCC + INVERTER) to $1200 or below??? Or do you think the EPEVER 80A x 2 + inverter is the way to go???
Any better solutions??
One of the other girl engineers thought we could take the MPP SOLAR 2424 they sent and use that on the left 5 panels and then just get a EPEVER 80A for the right 5 panels and hook both the 2424 and the EPEVER 80A directly to the battery ... that actually sounds like a better plan unless someone can come up with better ... (the 2424 has a built in 3KW inverter)
THX ahead of time ...
