We are attempting to assess the ability of our solar panels to recharge (“refill”) our batteries and are confused by the Amp-Hours being reset to 0. Example: over last night the Amp-Hours consumed were 21.6 (-21.6 showing in the app). When sun hit the solar panels the current and power moved to positive values and the Amp-Hour reading started slowly moving back to 0- exactly what we were expecting to see. Later the Amp-Hours displays as 0 while the current and power are both still positive. No where near enough charging had happened to fully recharge the batteries. What is going on? It would seem the Amp-Hour display should show cumulative totals until fully charged again, but obviously not. Help please?
