If a 1000 watt inverter feels like it’ll leave you rationing power, Renogy’s P2 2000 watt pure sine inverter is the step up. It’s still true pure sine wave output — safe for sensitive electronics and motors — but with double the continuous capacity, so you’re not stuck choosing between running the microwave or charging your tools.
At 2000 watts continuous, this inverter can handle a microwave, a coffee maker, power tools, a small window AC unit for short stretches, or several smaller devices running at the same time. The P2 series also carries a solid surge rating for the split-second power spike that motors and compressors need to start up, which is where a lot of cheaper inverters trip out and shut down.
The tradeoff for that extra capacity is current draw. A 2000 watt pure sine inverter pulling full power from a 12V bank draws upwards of 170 amps, which demands serious cable gauge and a properly rated fuse right at the battery. If you’re running loads this size regularly, it’s also worth considering a 24V battery bank instead of 12V, since it cuts that current draw roughly in half for the same power output.
Before you buy, it’s worth confirming 2000 watts is actually the right number for your loads rather than just picking the bigger option. Our guide on Inverter Sizing walks through how to add up your real power draw so you land on the right size the first time.
