I was also going to do this, but if it's only for load shedding, then you do not need anything more than a 500 watt job and go find an old UPS (plenty lying around), they work like a dream with some decent batteries.No but would be quite interested in what other people are using... contemplating building my own inverter instead of buying the whole shebang
At least someone that knows battery technology. Just to add - I've been through a vigorous battery testing spree for a blog. Two batteries (Silver Calcium) Deep cycles that stand head and shoulders above anything else, the Excis 102 AH and the Deltec 102 AH both with a R.C of 180 mins. The Excis seems more stable but delivers the same discharge performance as the Deltecs. Deltecs are cheaper and preferred by solar system installers. I also tested the Enex X31 battery but they do not run as long as the Excis and Deltec. They are only 100 AH but also a R.C Rating of 180 mins.Most inverters are similar and mostly use the same circuitry, the secret is how you treat your batteries.
Never pull them down further than 50% which is 12.05 volts else you create permanent damage.
The same goes for charging the batteries, do not use a Lead Acid charger on a Silver Calcium else you shorten your battery life by as much as 75%
I bet you have it less than a year.I have a powerstash markII inverter at home. works pretty well
Yip - only a couple of months now...but I've had my Ellies Inverter for over 5years now with exactly the same batts...I bet you have it less than a year.
When you see a store selling lead calcium batteries claiming them to be 'deep cycle' yet it clearly warns you ( on battery label) not to discharge it below 50%, this must ring alarm bells.
It's fortunate for these guys that 99% of the market have no knowledge in this department ....
