Update: I just did a comparison of the power reported by Sunsynk as imported vs the prepaid meter tally over the last 3 months. The difference between the two is 7% amounting to 25kWh (Eskom 25kWh more than Sunsynk). Therefore, the Eskom meter is not tallying the continual consumption as I originally thought as it reactive. Thank you so much for the assistance and comments above. I greatly appreciate the time and effort taken. What an amazing forum.

Thanks Andrew, I have reverted to switching off the mains feed to the inverter in the mornings and switching it back on in the evenings as you mentioned, but this defeats the whole point of supplying non essentials should there be enough surplus power. I did also consider installing a contactor driven by the auxiliary output that I use for my pool pump. This is configured to only switch on when a defined SOC is reached and a certain number of watts of solar power is available. Maybe you could explore using this functionality in the workaround.

It is actually using municipal power. I used a PowerUp 5kW inverter for many years and since switching to the Sunsynk we are consuming more Eskom power.

Thanks P1000. That makes perfect sense. Is there a way to reduce being billed for this reactive dumping without power factor correction capacitors etc? I saw there is a PF adjust possible on the inverter but surely this would only apply to certain operation conditions of the system? Thanks again for the response, I look forward to further discussion.

Hi Jacques, Thanks for the response. Zero-Export is selected and Grid trickle feed is set to 0. Regards, T.

Hi all, I have a Sunsynk 5kW connected to 5kW of solar and a 10kWh Revov battery pack. Since installation (about 1 year ago), I noticed there is continual draw from utility (Eskom) of about 250W when there is ample solar and/or battery power available and the inverter reports 0W import. This amounts to about 5kWh of purchased power a day or 150kWh a month of wasted money through purchased electricity. The current drawn from utility can be seen on the attached graph (Image2). One can clearly see the continual draw of about 1.2A which can be verified with a clamp meter. This current drops to 0A during loadshedding, which can be seen in the graph (in this case 2-4am). Interestingly, the inverter shows 0W draw from utility at the exact time it is actually consuming about 250W (Image1). Has anyone noticed this issue and found a resolve? I would greatly appreciate assistance, please. Regards, T.
