How impressed you are looking to be = $$.
On the low end and if you want an integrated ac charger (usually) and auto transfer switch for generator and shore power pass-through, sigineer is robust. Aims is made by sigineer as far as i can tell. Almost twice the price..... 400 and up. 600ish $ 3000W
People like the mpp solar inverters. Decent features, all in one of using solar, if not dont use solar and its a cost effective inverter charger.
I have to say for lower cost i like the sigineer. Have installed them and aims, not bad.
If you want the good stuff i install for clients who have more budget room than myself.......
Hands down outback inverters. A vfx3024 or 2512 or something would run 1200-1400$ plus a interface/display and battery monitoring if you like.
The samlex evo is good equipment they make a range of inverters.
And RV people like their schneider/zantrex inverters. Freedom, conext, pro-sine etc. Great stuff.
Dont forget magnum. Magnum inverters are as robust as any and nearly bomb-proof.
Outback has had the lowest standby and higher efficiencies than most off grid hear. Programmable to suit most any situation common to RE and power delivery from batteries. I have only had one single inverter need service out of scads of outbacks since 2011.
Fx inverters require 2 stacked or a transformer to output split phase 240vac. Only drawback, but they make a 4000w radian 240v inverter. A little large physically, for an rv..... same for an sma sunny island, need two or a transformer and large...
The most compact ones for your use would be the fx, evo or sigineer/aims, prosine, freedom amd conext are alittle big maybe not sure.
