In this video we take a look at the Grid Tied Solar Power System I have installed to test various solar components.
Here we look at the installation of the Enphase M250 Microinverters, the Envoy Communication Gateway and the Enlighten Manager Website to monitor solar power performance and production:
https://enlighten.enphaseenergy.com/public/systems/sC2L462776
My system components:
* SolarWorld 250W Poly, SW 250 Poly
* SolarWorld 250W Mono, SW 250 Mono Black
* Renogy 250W Mono, RNG250D Black
* CanadianSolar 250W Poly, CS6P250P
* 4 x Enphase M250 Microinverters
* Envoy Communication Gateway
* Outback Radian GS4048A Inverter
* Radian GSLC175-AC-120/240 GSLC load center
* IronRidge Solar Panel Ground Mount System
* MATE3 System Display and Controller
* MidNite Solar Battery Enclosure
* 4 x MK / Deka Solar 8A31DT AGM 105 AH (20HR) Dual Terminal deep cycle batteries.
In a future video we’ll investigate the issues with Grid Zero and Microinverters
Hybrid grid tie with battery backup.
