I have 3 cars, a tractor, an RV, 4 boats, etc. A few years ago I tried an AGM battery and liked it so much that over a 4 year period I converted everything to AGM. The first to go was a boat battery. Then, several had charging issues due to sulfating. I must say that I have a VG automatic smart battery charger that has AGM settings, so I did everything right.

Bottom line is that I have basically converted them all back except for the jetski, that IMHO gets too much bouncing for a lead acid battery. Economically the wet battery is the best choice - just take care of it.

I have read a little bit more about solar...

- it appears that RV solar qualifies for federal tax credit (30%) including batteries

- I am still thinking about AGM. Would Trojan T31-AGM 12V 100Ah Group 31 Deep Cycle AGM work?

http://www.amazon.com/Trojan-T31-AGM.../dp/B00NY0S8SY

- Are there any cons to install the panels on the roof of a new White Hawk like this guy is showing? Seems like not that complicated job...



- Would this be an issue to have the panels in front of the trailer (on the roof) and the batteries in the back of the trailer? Somebody mentioned that the inverter needs to be as close to the batteries as possible. Is there such a rule for the solar panels and the batteries?

Many thanks!

Solar Grounding

All,

I spawned a new thread to discuss the positive and negative grounding of the solar systems touched on by tawoo & gypsmjim.

It is here for those that are interested: https://www.jaycoowners.com/forums/f7...ing-30445.html

Thanks,

David

There are a few basic rules for SOLAR installations:

- The INVERTER (12VDC to 110VAC) needs to be as close to the batteries as possible.
- The SOLAR Charge Controller (PWM or MPPT types) need to be as close to the batteries as possible.
- The higher voltage portion of the SOLAR circuit (Panel/Controller/Batteries) is the SOLAR panel, so the longest wire run should be between the panel(s) and the SOLAR charge controller. Higher voltage means less of a voltage drop.

There are a few basic rules for installing SOLAR on a TT/RV:

- The INVERTER (12VDC to 110VAC) should be mounted as close to the batteries as possible
- The SOLAR Charge Controller (PWM or MPPT Types) should be mounted as close to the batteries as possible.
- The longest cable run for the installation should be between the panel(s) and the SOLAR Charge Controller. This is the highest voltage section of the circuit and will encounter the lowest voltage drop.
