We decided on the portable option. Found a Zamp 200w system for a great price. The cougar was equipped with an AE connector which made the portable connection super easy. Portables come with an integrated controller so no issues with where or how to connect. Storage is no issue, unit is very compact an set up time is less than 5 minutes. Even if it's only partly sunny the solar works great keeping our batteries topped off. We also installed an inverter located at the entertainment center so we can use the TV/DVD off grid as well as recharge the laptop and cell phones. Using the generator now is a rare event, limited to DW's hair dryer
Recommend a 100w minimum solar kit. Larger if it's affordable.
