1 150/60 amp mppt
150 feet of 10 gauge solar wire
12 12volt Deep cycle marine batteries/Lead Acid
20 feet 2/0 wire
20 feet of 2awg wire
1 3000 watt pure sine wave inverter
1 5000 watt pure sine wave inverter

I thought it may be fun to see all the possibilities we can come up with and what am I missing !!

 

[crossy]

Operating voltage of the inverters?
Ah capacity of the batteries?
O/C voltage of the panels?

 

[Rednecktek]

Yeah, we need more info, otherwise you're just going to get:
2s2p 300w panels to 40a MPPT
3s2p 250w panels to 60a MPPT
4s4p batteries in 48v to 5000w inverter
3Kw in the spare parts box
10AWG wire from panels to SCC's
2AWG from SCC's to Batteries
2/0 to inverter, dual wires on each leg

The more important question is when can you drop all those parts off at my camp? ?

 

[gnoeld]

Operating voltage of the inverters?
Ah capacity of the batteries?
O/C voltage of the panels?

12V inverter
100Ah batteries
O/C Voltage on the 250 watt panels is 37.6
on the 300 watt panels is 18 (supposedly) These are the cheap Chinese flexible panels so I question the OCV

And about 5.2a for the Imp? Yeah, we've seen those before. Total lies.

How cold is the beer?
I may swing by

Yes we need more information about the capacities and other specifications. I would want to know the manufacturer to determine the quality. I have room in the trash dumpster.

Primarily inverters and SCC's, although battery make & model wouldn't hurt.

You can stop now. my dumpster is full.

 

[SparkyJJO]

Holy crap a 5000W 12V inverter?

That's well over 400 amps on the DC side. Yikes.

 

[ericfx1984]

Holy crap a 5000W 12V inverter?

That's well over 400 amps on the DC side. Yikes.

5000 x 1.25 = 6250w on the DC side

6250w/12v= 520amps

This is assuming that he does not push it into overload.. or peak

Hey Doc, I'm still in the room. Will I survive or do I have a problem?

 

[gnoeld]

Has everyone given up?

 

[Rednecktek]

2s2p the 250w panels to the 150/60 SCC, run out of 10AWG wire
2s the other 250w panels to the 100/40 SCC if you bought more 10AWG wire
Put the "300w Flexible" panels in the trash can.

12p the batteries no greater than 12" apart to a bus bar with 2AWG wire, run out of 2AWG
3x 2/0 wires from bus bar to 5Kw inverter + less than 3ft, run out of 2/0 wire
3x 2/0 wires from bus bar to 5Kw inverter - less than 3ft, run out of 2/0 wire

Put 3Kw inverter in storage as a "Spare"

 

[gnoeld]

I laughed so hard when I read "Put the "300w Flexible" panels in the trash can"?

3x 2/0 wires from bus bar to 5Kw inverter - less than 3ft, run out of 2/0 wire

Put 3Kw inverter in storage as a "Spare"

I calculate the 2s2p would be 60 volts and 18 amps
2s would produce 60 volts and 9 amps
Sound about right?
