Only had it for a few weeks so cannot judge it harshly.

It appears to handle the power draw quite well,

the battery meter does lie a little bit -when the

battery is fully charged, and the power cuts out,

it drops down to "half charged" but i think this is because

being such a beefy charger, it maybe requires a few more

batteries on it, as the voltage of a single large group 27

lead acid battery stabilises around 12.36 volts during use of battery,

there is nothing wrong with either the battery or the inverter,

I think its just needs a few more batteries, it is a big

inverter and is desined to run/charge more than just one battery.
