Hi,
I have an external 16kW air source heat pump (Samsung Gen 6 with Kodiak Joule cylinder). It's currently running on power supplied by a solax hybrid grid-tied inverter connected to 7 solar panels (no battery). We are struggling with winter running costs in the absence of energy storage.
I do however have an off-grid array of 10 x 400W panels with an off-grid inverter. This has mains electricity feed only on the input side. It runs numerous circuits in our house. It also has 24kWh worth of battery storage and I would love to find a way to use this to help with the ASHP energy consumption.
I can't connect the grid-tied inverter to these batteries but was wondering if I could use a downstream transfer switch to switch between the grid-tied, batteryless inverter as an input source and the off-grid, battery-connected inverter? I tried a test and all seemed to work beautifully with one exception: the Samsung controller on the indoor cylinder displays an 'E101 zone 200000' error message after a short time.
Am I naive in just switching input to the heat pump? Does the water cylinder need to be powered from the same source? Or do I just need to reset the cylinder?
I've looked everywhere for a similar thread but no luck. Any advice greatly appreciated.
Thanks
Terry
