You don’t have to be an industry to use Industrial sized batteries, as a matter of fact the cost of ownership always works out at less per year with Industrial batteries. Why? Because the plates are thicker so they waste away much slower and longer than the smaller batteries.
Another very interesting fact is that while they give you almost twice the life they don’t cost that much more than a bank of smaller batteries of the same amp hour rating. The thing to remember is you’re really just buying lead. There’s a direct correlation between amp hours, weight and dollars. So very often the industrial size battery is just a little more cost, and more than twice the life, of the smaller batteries.
All batteries pose some sort of “sticker shock” to the first time battery buyer, which is understandable as the price of lead is quite high these days.
The real challenge with Industrial batteries is the sheer weight and size. Remember you have to be able to move these and often this requires heavy equipment… so it’s going to be difficult to get 5000 pounds of batteries into your basement.
If you’re planning a new system, do yourself a favor; plan ahead to accommodate the task of moving the batteries with the right equipment. Placement will be the key, even a battery box outside the wall from the inverters might provide good access to moving equipment.
When you consider placement, remember, batteries like to be around 75 to 80 degrees F. So if you are considering an outside location, an insulated box will not keep them warm. Insulation just holds heat and batteries generate little heat themselves, so without some heat source you’ll just be insulating cold air.
