I am looking at more effective ways to use the excess PV rather than feeding it back to the Grid. One of the options that I am exploring is to divert the excess PV to the electric booster on my Solar Hot Water system. My PV installation is as follows:
- Envoy-S monitor
- Panels 16x320W 4 LG neon
- Enphase Microinverters.
- 3 Phase Power
- Net Power meter, Time of Use
I use a python script to log the following Envoy-S data at 15s intervals. The Envoy also provides Current, Reactive and Apparent Power for Total Consumption, Net Consumption and Production
- Total-Consumption in watts (use)
- Total-Consumption watt hours today (cumulative)
- Net-Consumption in watts (import or export)
- Net-Consumption watt hours today (cumulative)
- PV Production in watts (Solar PV)
- PV watt hours today
- PV watt hours lifetime
I want to divert excess PV to a Hot Water System using data from the Envoy-S.
My plan is to use the data from the Envoy to drive a triac or SSR to divert the excess power to the hotwater booster element. I am thinking of using an ESP32 (have some lying around) as the the TRIAC/SSR controller.
I have 3 main questions, that I am hoping some one can help me with.
In terms of Open Energy Monitor is my enphase microinverter system classified as Type 1 or Type installation.
Can I use the data from the Envoy-S to drive a controller and triac without having to install a mk2pvrouter or emontx3 and associated CT’s.
Any help or advice would be greatly appreciated.
