Selecting a Power Generator to Recharge the Battery

Any power generator (solar, wind, fuel-driven generator, etc., or any combination of these) selected for a hybrid power system should be able to fully recharge the battery once per day, thus limiting the battery cycles to one to two times daily.

Due to the inefficiencies of power generation sources, there is a general rule of thumb for determining the power generation required to recharge a battery:

Total Battery Capacity (Wh) ∙ 1.25 = Required Generator Power

Example: STIKmann’s Power Generator

Applying the formula to STIKmann’s camping situation yields:

680 Wh ∙ 1.25 = 850 Wh
850 Wh ÷ 12 V = 71 Ah
STIKmann should use a generator that is capable of producing at least 850 Wh (71 Ah at 12 V) of daily power to keep the battery charged and cycles to a minimum.
Optimizing Power Generation Options

Solar photovoltaic (PV) panels or other power generation sources can be used in a portable hybrid power system. The open architecture of the Solar Stik Hybrid Power System allows users to add as much PV input as desired. The system’s battery bank captures and stores the power produced by the PV array and/or other power generation sources.

In a properly sized system with a fuel-driven generator, increasing the power supplied by PV arrays reduces the burden on the fuel-driven generator, thereby reducing generator runtime and fuel consumption. Adding PV arrays provides free power during daylight hours that effectively supplements the power that must be provided by the generator.
