Batteries are an important part of off-grid solar systems, back-up power systems, and RV & Marine installations. Sometimes you can find what you need locally, but the batteries we carry are for when you are ready to move to the "next step" in battery quality.
Choose the right batteries
Batteries are the reservoir of power in an alternate energy system. The right battery choice is important to ensure your power system performs properly, and that system life is maximized. We recommend deep-cycle batteries for all alternate energy power systems. Quality industrial batteries offer longer life and better protection from abuse than low cost automotive batteries. If your budget is tight, select the deep-cycle 6 V batteries - they are economical yet offer good cycle performance.
Sizing your battery bank
The size of your ideal battery bank depends on your loads and the charging system. Deep-cycle batteries are like any other batteries - the less they work, the longer they will last. So a bigger bank not only gives you a larger reservoir, but also offers longer battery life.
Typical installations have a balance of 100 amp hours of battery capacity per 3 amps of solar panel current. An inverter/generator system will have a battery bank that may run the whole house for up to 3 days without recharging. In the long run, the general rule is to choose the largest, best quality bank you can afford.
