First of all Solar Photovoltaic panels produce DC power, which varies in accordance with the suns intensity and angle to the panel, while as yall know the utility furnishes AC, so it requires Inverter technology to change the raw DC into the proper AC voltage and frequency. The so called "grid tie" systems essentially sells the homeowners produced solar energy (when and if its producing) back to the utility. HOWEVER if the homeowner wants a stand alone system that can power his home if the utility is down IT COSTS MUCH MORE since he has to store the energy in batteries and then Invert it into useful AC plus have all the necessary and safe transfer methods.. Im NOT getting into economics or feasibility but ONLY explaining a bit about solar and grid tie versus battery backup for energy storage.

After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
