Thank you very much for your help, I really appreciate it. Now I can make my purchase. One more question do I need to add the battery isolator switch to my system

There were two automotive batteries that were connected to the wheelchair lift, they also look like they run to the starter battery, but are not required to start the vehicle there's a separate battery for that. I disconnected them when I removed the wheelchair lift. And traded one for my...

The taped negative and positive wires were connected to the wheelchair lift box, I didn't want to cut them just in case I could use them for my solar setup.

I will store my batteries in that battery storage compartment which is located on the outside of the vehicle. It's a 2009 ford E-450 that I've converted.

I was just going to use the batteries to power the inverter for now

Is my system correct. Will be 12v and wired parallel, includes 2-240w panels, 40a mppt solar charge controller, 1500 pure sine wave inverter, 2-105ah agm batteries, 250a breaker, gland, y branch connectors, mc4 extension cords, on/off switch. 40amp fuse for charge controller, 20a inline fuse for...

Is copper tinned wire ok to use?

Ok great, thank you very much for your help.

One more thing is there a substitute I can use for butyl tape, where I'm located it's not sold in stores it has to be ordered.

What you sent me says 200a fuse and #2 Guage wire

I purchased the 250a breaker for between battery and inverter. The charge controller will be about 6-7 inches away

Ok thank you

My wire will be 6 inches apart from battery to battery, 9 inches apart from battery to inverter

I will not be upgrading as I have other sources of power

Everyone is telling me different stuff I was told 4awg and 150a breaker. I'm making sure I have the right information so I can purchase the wire and fuses So I need 1awg and 150A for batteries to parallel and batteries to inverter and 8awg is good for controller the distance should be between...

What I have so far. 12 gauge awg red/black wire 1500 watt pure sine inverter shore power outlet z brackets 60 amp charge controller cable entry gland 12 way fuse block 2 -240 watt panels 250 amp circuit breaker

No panels are sun power

Can I use this battery for inverter?

So I will need 2 Guage instead of 4

Ok, so you're saying I'm only missing the wires and fuse that goes in between the battery. SCC is mppt. Was thinking about using 10 and 4 gauge wires

Are you serious it stated SCC was mppt. Panels are actually suntech. Was thinking series. Will buy AGM batteries and yes it's for a vehicle

I also have 2 generators and shore power. Don't want anything interfering with my alternator since it'll be expensive to change.

Don't remember how much I paid for it. How can I make sure the SCC is mppt. Will return this one.

No purchased on ebay Panels pic

So I don't need a Y or T branch connector
