WatchPower 4+

IF you can manage to get your account created and actually get your inverter connected to this app, then you have a few basic functions which are nice. Primarily, you can set your battery parameters in the app rather than using the inverter buttons. You can also do this remotely. The setup process is a complete nightmare of connection failures until it finally connects. Took over a year for me to actually get the app to connect to my inverter. It’s awful.

Other than that, the other functions of this app are useless. My “overview” page does not display any information. Just 0Kw. Never changes.

No graphs or anything for power usage other than some very odd timestamps of non-important power fluctuations or something like that.

Can’t recommend.

The app doesn't show notifications on iPhone outside the app, which is a big problem when power goes off or battery goes low, you can't see notifications unless you open the app!
Other wise the app is good.

This is an good app for monitoring and configuring solar and backup battery setups, with one very important omission. Not being able to set notifications when a power source goes down is a big mistake. I sure hope the developer adds this - it is essential! I will change my rating to 5 stars if it is added.
