To get the best performance out of your solar battery system, install it in a place where the temperature wont exceed its operating requirements (i.e., dont install it outside if it cant operate below freezing but you live in the Northeast), and be sure to follow recommended operating procedures when using the battery (i.e., dont override factory defaults that could cause the battery to go to a greater depth of discharge or cycle more frequently than its designed for). The battery's storage capacity. PWM controllers are more affordable and work well for small solar panel systems. WindyNations sealed lead-acid batteries are made with pure, virgin lead (not recycled like lower-quality batteries), which makes them ideal for deep, repetitive charges. The protection method varies according to cell chemistry: NiMH batteries require a circuit that detects a change in voltage or temperature, where Li-ion cells require a two-stage constant-current/constant-voltage charge method. Some controllers also prevent battery over discharge, protect from electrical overload, and/or display battery status and the flow of power. Contact them at 800-919-2400 or techs@realgoods.com. If you want a . The panel wattage is sized based on your batteries AH rating and the amount of good sunlight you get in a day for your area. Failure to use a charge control circuit will adversely affect the performance of your battery over time in the best case scenario. First it's best to know how many amps you usually use, then have a battery bank large enough to cover the usage for 2-3 days. This happens in case the power consumed by a load is exceptionally high. The sulfur molecules inside the battery get discharged and begin to cover the lead plates. Known for their low life-time cost, and higher efficiency, lithium-ion batteries are seen as the batteries of the future. Without go to college for the next ten years, is there a simple way for me figure this out.
