Top 3 Batteries For An Off-Grid Energy System

2) Industrial or Forklift Batteries

A battery bank that uses one or more industrial batteries follows the opposite philosophy of a golf cart battery bank. Instead of relying on multiple strings of smaller batteries, you use a few or even one battery to store all of your energy.

Because these batteries aren’t usually manufactured to standard dimensions, you will have to have one made that is just right for your needs.

Or you can try to find an old industrial or forklift battery that’s the correct size for your system and use that.

Like golf cart batteries, there are sometimes ways to get free or cheap forklift batteries.

One way is to call up or visit industrial companies and see if they have old or “dead” forklift batteries. Offer to dispose of it for them or pay them a little bit. If they agree, you can then recondition the battery and use it instead buying a new pricey industrial battery.

But if you choose to get a new custom made battery instead, you should expect to pay quite a bit. But the good news is these types of batteries are typically built to last 15 to 20 years.

Other thing to consider are:

  • These bigger batteries will be heavier and more difficult to move around.
  • There may be advancements in battery technology that could make the battery obsolete in years to come.

But if you don’t mind making a significant investment upfront (anywhere from $2,000 to $10,00) and are alright with spending time keeping your batteries in top condition, then industrial batteries might be right for you.
