Short Inverter Update

The old Trace 2024 modified sine wave inverter for my house has been replaced with a true sine wave inverter. ( WZRELB 24 DC to 120 AC 6000 Watt surge) It’s been in use long enough that I have some feedback.

On the plus side: LED lights work properly. They were dim and burned out quickly with modified sine wave -probably not too safe. The true sine wave runs induction stove tops while the modified did not. Things like ceiling fans and microwave ovens run much quieter. There’s no longer a faint buzz sound from some audio equipment. 

On the downside the new inverter is a bit more sensitive to temporary low voltages. For example, there will be a lot of things drawing power. The induction stove top is a big one. Then the ½ horse well pump kicks in causing a sudden surge demand. If the batteries are on the low side to begin with that can trip the low voltage inverter safety and shut it down. The modified sine wave inverter handled low voltage draws a bit better. 

To fix that I can either turn the battery charger on or turn the inverter off than on again. It’s not a big deal. 

All in all, the gains are well worth the trade offs.



  1. Sounds like to me you need more batteries for the loads described.

    Rebooting the inverter often isn't good for the inverter.

    Glad to hear its working well with your stuff but the low voltage safety bothers me.

    1. I'm going to take the induction off the inverter and put it back on the grid. That should eliminate any problems. Over the course of the day the induction stove doesn't use a lot of power but the power it uses is in big bursts.
