Looking for inverter recommendations.

[huffdawg]

I have just come across 2 8D batteries. I'm looking for an affordable and reliable inverter.
Also what is the best way to connect the batteries for use on an inverter,in series for 48 volts or parallel @ 24 volts.
I'll be using it to run my boiler and pumps in the event of a blackout.

Thanx Huff

I have a 1500 watt unit that I have hooked up to my RV batteries. Three 12 volt deep cycle. I recommend a pure sine wave unit if like me you are skiddish about burning something up. I originally installed a modified sine wave unit but the circulators hummed and the Eko control was strobing.

The unit I have has the built in battery charger and automatic switch over when power drops out. It also has a remote control. Actually I don't use it since I installed my propane back-up generator but I decided to keep it. Right now it is being used an an expensive battery maintainer for the RV batteries while the RV is hibernating in the shed. This is the outfit I got it from but upon a quick glance, I didn't see mine in there.

The speil I got from one salesman was that you needed a much higher wattage than your load if you used a modified sine wave vs pure sine wave. Don't know! There are members here that actually do know. We'll be hearing from them.

I'll echo the pure sine observation. Modified sine seems to not work well with heating system components - less than full circulator speeds, for instance. I'm using a full-sine computer UPS at the moment.

RVs use inverters in the right power range and I think there are some that aren't outrageously expensive.

thanx Bill. By the way how is your new controller coming along .

Like pulling teeth.... We have a really nice new enclosure design, and with any luck I'll be able to get a more powerful and marginally less expensive card set. Everything takes longer that you might expect, though :-(
