"a.k.a Wants -VS- Needs"
This page tackles the age old dilemma of your Wants vs Needs. Before you start picking through the list below, please keep in mind that these are add-ons....Above and beyond, the package you picked ( unless you chose "custom" as your package). S0, to clarify, if you picked package Model II which comes with 1 battery included, but you want/need 2 batteries, then you would just add the price of 1 battery from the list below, because Model II already includes 1 battery.
Another situation you may run across is (for example) say you chose Package II, but want/need a larger refrigerator?.....Keep in mind that other items may need to purchased to accommodate your new appliance want/need. In order for your new fridge to fit (literally), you will need to advance to our 36in front door and that may not be all, your PV system may need to be advanced to support the larger appliance and still allow you to remain off-the-grid... The best thing to do is to look this page over, then contact us with your Package Choice and your wants/needs. We will be happy to help you with your choices and be able to tell you if your wants/needs require other items to be added to your list to support your wants/needs choice.
