String meters measure DC power (voltage × current) and are for monitoring only. Keep the total-power meter (0) as the site's PV meter.

The energy value is missing here for each MPPT.

Thanks for the review, but are you able to descibe what is missing here?

The power each MPPT is producing is getting calculated because there is no register produced by Sigenergy to getting the exact power number.

Or did I miss here something?
