An odd behavior is seen on the Deye 8K when the electricians were testing for the CoC. Basically they turned off the main breaker at the DB to simulate a grid off scenario. The inverter kicked in and started supplying from battery. But the indication light at the main breaker did not go off as it was expected to indicate a grid failure/disconnect. So when they started to troubleshoot, they measured a voltage across the Live and Neutral on the grid input of the Inverter. This seems to indicate that the inverter is not disconnecting itself completely from the Grid Input and is feeding back from power on the input. The settings (either zero export to Load or zero export to CT) did not seem to make any difference. They had installed a contactor on the Inverter output to bridge Earth and Neutral and when they turn that contactor off, the voltage between L and N on the Grid Input is around 130V. And with L and N bridged it becomes 230V. So it appears the voltage is coming from the inverter when it is off grid and the grid Neutral/Ground has been lost. Has anyone else seen this behavior? None of the setting changes on the Inverter seem to make a difference and the 230V is always there, though with very low current since the LED indicator at the DB is On but extremely dim v/s when the grid is actually On.

Using a Deye 8k with 2x Volta 1. Just added a third. Performance so far has been great. It has been 4 months and no issues so far. Easily runs an induction hob plus oven plus heat pump water heater through loadshedding.

Having the same issue with a newly installed Deye 8k and two Volta 1 batteries. When coming back out of loadshedding neither grid not PV charges the batteries. The battery state shows charging but the actually % doesn’t change at all. Anyone seen a resolution to this issue ?

Hi folks Got a house recently and looking to add solar for powering our life including cooking. Currently remodeling our kitchen and plan to install an AEG induction hob. Planned to install sunsynk 8kw inverter for our solar but some of the installers claim it can’t handle an induction hob. The one we are looking at has a max power of 7kw but typical usage of 2.4kw. They are recommending to use Victron instead. do folks have experience with sunsynk and induction hobs ? Would there be any issues here to go with sunsynk?
