Good Inverter - Beware of those unfamiliar with Inverters
Beware of all those talking about failures of the inverter - one guy says that he returned his, because two 70Ah batteries couldn't power it to run a 1/2 horsepower motor.
Well…guys, there are a few things you need to know about inverters before buying a big one…which does NOT directly substitute for a generator! The little ones are WAY DIFFERENT than the big ones.
First off, at 2500-watts, you are pulling 200+ amps across the wire…so, unless you are hard-wired with some 4/0 solid-strand wire, you really need to go with DOUBLE 4-AWG strand wires…basically, buy TWO sets of 4-AWG jumper cables, and after you cut the ends off both, then run double-strand (both red AND black) of a complete set to EACH POST of the inverter…yes guys, that’s a LOT of wire…and due to heat, I wouldn’t run that more than 5-6 feet!
Now…batteries…let’s laugh at the guy trying to get 1600 watts of batteries to run a 2500 watt inverter…and consider what you REALLY NEED…for deep cycle batteries rated on the 20-Ah system, and rated at, say 500-Amps, then buy 6 of these and wire them in PARALLEL circuit to power the inverter. Yep…$600 in deep cycle batteries! Now, you have enough batteries to power the inverter for 2-6 hours, depending on loading, before you will need to recharge your 6-battery bank. Plan on a charger that can throw 50-100 amps into the charge…so your little $50 Schumacher charger is NOT going to charge this battery bank overnight! Try more like a $300 charger to charge them in 12-hours…or, if you want solar, good…you need to throw about 70-amps of charge into these for 12-hours solid…so that is $300-$500 in solar panels. Also note…batteries get weak after enough cycles…so pay attention to your charge circuit…and a charging circuit MINDER isn’t a bad idea, either!
How do I know this? Because these are all the big troubles encountered when I was a Director of Engineering for an RV Manufacturer…and when you get over 1500-Watts of inverter involved…you start playing by a whole new set of rules! It is MUCH CHEAPER to go with a 3000-watt generator, than to even CONSIDER getting a 2500-watt inverter.
This is a good inverter…but buying one this big and not knowing how to care for and maintain it, is like buying a big chemistry set and giving it without supervision to your mischievous 12-year old…it is NOT a good idea.
