150V DC - 230V AC Inverter Ideas.

DC-AC Inverter Ideas.

I have a 48S 50ah Lifepo4 pack with a nominal voltage of about 154V

I'm after ideas for an 230V AC inverter of about 3-4kw capability that will run from the above DC source.

I'm struggling to find anything with the right input voltage range apart from some exotic military grade/price stuff.

See example below.

Might be something here that's workable:

Perhaps this:

is one with a 120-430v DC input range for the MPPT stage and will run without battery storage - so you might be able to hook your battery to the solar panel input.

For a grid tie system you can use a regular PV inverter that is capable of zero feed in. Just be aware that most inverters are limited for ~13amps or so per tracker, so 2kW in your case. If you need more than 2kW you can use one that has 2 trackers and connect them in parrallel to your battery
