Do smaller Inverters use Less Energy? 200MAX vs AC300

[markieboy711]

I have three AC200P units and they are solid, but need more battery. Considering both the 200MAX or AC300.

I am wondering if one has an advantage over the other as far as using less energy to run itself (overhead usage).

Hi @markieboy711,

The smaller inverter, the less power will be used if they power the same wattage device in the same time.

Here are some discussions about AC200 and AC300 for your reference

Undecided between AC200 or 300

Buy yourself one of the tools to measure your use over time for each item… That way you can really know how much energy your stuff uses over time. Obviously if conditions change you need to retest. an AC unit will use more energy in August than it will in February. Then you decide what you want to power, and for how long. you can adjust them manually or automatically. I.e. power your ac with the AC200Max for an hour then shut it off manually. Once you know your needs for your gadgets, over…

I had to choose the AC300 because I needed more power and the AC300 gives 3 kW (120 VAC at 25 A), and it allows up to four B300 3 kWh batteries for a total of 12 kWh of power. Plus I also needed 240 VAC which uses two AC300 and the Fusion Box Pro. The second AC300 adds 3 kW more for 6 kW of 240 VAC at 25 A. Adding four more B300 gives up to 24 kWh.

These are the main advantages of the AC300 over the AC200P or the AC200MAX.
