Question Hybrid Pure Sine Invertors

[MemoriesByTheMile]

You can have to small an inverter, but never to large. In standby mode, one inverter, rather than 2, will draw less power, so one big unit makes perfect sense.

Parasitic draw can add up quickly. We have twin Outback Power 2800 watt inverters with their Outback-PSX-240 transformer configured for load balancing - we haven’t measured the exact amount each of them has in parasitic draw, but it seems to be around 1amp each inverter.

Other downside to multiple inverters is loss of space.

Love reading here and learning.

Joe, if you want more power you can just get another MS 2812 and stack them with this kit/instructions:

Probably the most economical and simple method and you can still use your existing Magnum remote control. If you want to monitor and configure both units at the same time, you can install a second remote. The limitation, as others have mentioned, is your battery bank. Unless you make a major upgrade here (at least double your storage) you wont be able to make much use of your increased inverting capability.
