Features
Read full description

This simple app allows you to monitor and control your GivEnergy inverter(s). They should have static IP addresses, set either in the inverter itself or in your router. Up to four inverters may be connected, but the app treats them entirely independently, not as a 'plant'. To force the app to request the IP address(es) again open the iOS 'Files' app, select 'On your iPad/iPhone' then 'Inverter' and delete the file inverter.dat.

Verdict

The call

The clearest difference is in-app purchases: Inverter at none against Polar's 1. Inverter also leads on update cadence (every 10 days vs every 5 weeks) and iOS requirement (15.6 vs 17.4). On price, ads and device support there is nothing between them.
