Hello everybody,
I have a relatively new install that has had some teething issues. I'm trying to establish if how I understand things should work is correct and there is fact a problem or maybe everything is working as expected and I'm just wrong. Your input and advice would be appreciated.
Current Setup:
Sunsynk 8kW Inverter
15x 455w Panels
Freedom Won Lite Home 10/8 LiFePO4 Battery
CT Coil installed. Cannot confirm if in correct place other than installer says it is.
No feedback should be happening
Load Split:
Everything on load except geyser should be on non-essential load
Problems:
1. Prepaid meter trips.
- I have to turn off my Eskom Grid to get the meter to turn on again and see my unit count. If I turn Eskom Grid on again, it will trip within an hour.
- Grid trickle feed is set to 20w
- I have tried increasing this as high as 100w. Still trips.
2. Inverter appears to be blind to non-essential load. I believe all geyser usage is pulling from grid.
- It was initially installed as everything on essential load by mistake. Every morning I could see a grid spike at 05:30 when my geyser turned on and battery was depleted
- Since changing to non essential load I never see this movement.
3. I have unexpected usage according to flow screen when changing settings under System Mode 2:
- "Zero export" & "Limit to Load only" ticked. "Solar export" unticked. System works as expected but cannot see non-essential load
- "Zero export" ticked. "Limit to Load only" and "Solar export" unticked. All load appears to come from grid. PV drops to 0kW.
- "Zero export" & "Solar export" ticked. "Limit to Load only" unticked. PV shoots up to max draw and I get negative load to grid. I'm assuming this means I'm feeding back.
