What's New

The sample systems I've configured here are just that - samples. You may not agree that they are the best combination of components for your particular situation. Everything is a tradeoff when it comes to RV's and this area is no different. However, these should give you a good place to start when you configure your own system.

High-end System

 

For the individual who boondocks a lot, and wants a technically superior system, that is easily expanded.  This is a top-end system that no one would be unhappy with. Cost is not the major consideration - it is not cheap. If you really push your system and need the best, then this is (argueably) it.

 

  • Outback  FX2012 Sine Wave Inverter 2000 watt/50 amp passthru
  • Outback MX60 PV charge controller (MPPT)
  • Outback Mate Monitor
  • 4- Kyocera KC-120 (or 125’s when available) Solar Panels. Hook them in series/pairs if long wire runs. Best price/size/performance tradeoff. You can add lots more panels with the 60 amp controller.
  • 6 – LifeLine GPL-4C 6 volt AGM batteries (660 Ah rating)  or
    6 – Trojan T-105 6 volt batteries (675 Ah rating)

Medium System

 

For those who want good performance, but price is more of a consideration. The system is not as easily expanded as the high-end system.

  • Xantrex RS2000 Inverter (on 30 amp system), or RS3000 Inverter (on 50 amp system). Both are Sine Wave.
  • Xantrex SCP (System Control Panel), and Trimetric 2020 monitor.
  • Blue Sky Solar Boost 3024i  charge controller (30 amp MPPT). Can handle 24-volt input. Do not buy the remote display. If you want more expandability there is a 50 amp version.
  • 3 - Kyocera KC-120 (or 125’s when available) Solar Panels. Best price/size/performance tradeoff. You can add one more panel with the SB3024i controller.
  • 4 – Sam’s Club 6 volt Golf Cart batteries (410 Ah rating). Expand to 6 if you need more reserve, but you will probably want to go with an extra solar panel if you have 6 batteries.

Economy System

 

For those who want good performance, but price is the major consideration. The system is expandable, but uses lower-cost components.

 

  • Heart (Xantrex) 458 Modified Sine Wave Inverter 2000 watt/30 amp pass thru.
  • Trace C40 charge controller. PWM controller, not an MPPT. Can handle 24-volt input.
  • Link 1000 Monitor. Has cummulative amphours.
  • 3 - Kyocera KC-120 (or 125’s when available) Solar Panels. Best price/size/performance tradeoff. You can add three more panels with the C40 controller.
  • 4 – Sam’s Club 6 volt Golf Cart batteries (410 Ah rating). Expand to 6 if you need more reserve, but you will probably want to go with an extra solar panel if you have 6 batteries.

If I were building a new system for myself I would build the medium system with the RS2000 inverter (I would add a sub panel to use with my 50-amp RV). I would add an extra solar panel (4 total), and use 6 batteries.

 

My current system is the economy system, with a Heliotrope 30 amp PWM charge controller and four KC-120 panels.
