I have noticed that Solar Assistant considerably underreads my Grid used in the past eight months

Sunsynk app shows 1033 units used in the past eight months

Mogale meter shows 1008 units used in the past eight months

Solar assist shows 746 units used in the past eight months

that equates to a 38% under reading

Solar Assistant website "Contact us" doesn't work so I am not sure how to fix this error

Hey dude, [email protected] drop them an email they are very responsive and very helpful.

Is your system feeding back to the grid at all? I’ve read in other posts that if your meter is not capable of allowing feedback it records it as usage.

What system are you running at the moment one or more inverters? Whats your settings? Have you only been using SA for the past 8 months or is it recording incorrectly for the past 8 months.

Do you know which of the three readings are actually correct?

Need more info to help you diagnose here.

When i initially installed SA i remember that its figures for Grid did not include the inverter's own usage - so this may be part of the missing information
