Building a relay system to auto switchover from inverter to grid
Garrie, Funny thing, i lost a small power supply to on my DVR because of the switching. Every time i switch the DVR restarts. Then the other day the power supply said hello!!! I change it over to new power supply and now when i'm switching the DVR don't restart so seems to me the supply keeps its charge/power a bit longer before dropping.

Similar Inverters
I'm going to add in to this mix the MLT Powerstar. It's Bi-direction Hybrid Inverter, so it can export to the grid to, take from the grid if there is a short and mix. It's got it's own build in Islanding system and you can adjust the export settings to.

Transformer vs Transformerless Inverters
Oooooo yes!!! Al the way for the DIY guys. Easy to check inside and easy to work, on the moving, you will need a extra 2 hands. Hahahahaha. The bigger ones got wheels to move them around. What nice of this units is, if you want to upgrade to more Kw power, you just add the extra transformer unit at the bottem of this one and plug in the cables and connect the bars on the side. You can stack 3 of this transformer units on top, then it will make 24kw of power.

Transformer vs Transformerless Inverters
@Richard Mackay that still small. If you get the opportunity to check inside n MLT Powerstar inverter, then you will see a really big one. I wish you guys can see it. Pictures can't do it justes. The complete unit weight is 82kg where I think 70 kg is just transformer in side.

@Party Plant Your problem is that 105Ah batteries isn't really made for this sort of work and for that inverters. They will now last long. You need something like Trojan's that Plonkster mention or go the LifePO4 way. Way better and they will last you longer. @plonkster So far i remember and have seen they can run on FreedomWon yes. Drop @Stanley a msg. His a pro with this stuff and owns one.
