battery maintenance

Battery life easily exceeds manufacturers estimates

Recent research just released from Zaragoza University, Spain, by VerticalNews show that battery life, crucial to the economics of off-grid energy – can easily exceed or heavily undershoot the manufacturers estimates.
It all depends on how well you maintain your batteries. IF you baby them along, never falling below 50% power and charnging the regularly, then you can double the life expectancy.

Solar panels for sunless setting

A hunting lodge in Maine with two small solar panels, some old used car batteries,a quarter mile of wire and careful management. An old-timer explains how he does it in this video.

The old batteries are important – recycled from the owners car once he buys a new one. The Deep cycle batteries which we are told are the right product for this environment, in reality do not hold a charge over the winter when not in use.

Solar Charge Controllers

If you have a simple off-grid setup with just one panel or even a few solar panels and several batteries, the other vital ingredient is a charge controller that regulates the power going from the panel to the battery and shuts off power input when the batteries are fully charged.

This makes the process of running your own power station almost maintenance free.

When you are starting up its best to buy a medium-priced controller so that you can add a few panels and batteries to the mix before having to upgrade. The HQRP 20A Solar Panel Battery Charge Controller / Regulator 12V / 24V 20 Amp 300W with PWM Type of Charging retails at under $50 on Amazon.
