So for some power backup for fish tanks we would want a beefier system.. Something that can give more power, be charged easily indoors until the power goes out and you need it. Its going to need to be able to safely process a good bit more DC into AC power. Luckily the options out there are awesome, largely because of the green energy/solar movement.
So heres some things we will use...
The battery,
You can get some Nice long lasting AGM sealed batteries that will cost alot of money, but don't spill and have a great life span... I went cheap as I am storing this in the garage.... Walmart Deepcycle marine battery.Its a flooded lead acid battery similar to whats in your car, but can be drained deeper. It comes with a 2 year warranty...and costs less than $110.
