Hey everyone, given the recent video, I thought everyone would enjoy a look at the solar inverter lab I have access to.
First, an overview:
On the far left there is a breaker panel connecting the grid (three-phase 208V) to our PV simulators and power transformer.
Below the breakers is a pair of DC PV simulators.
In the middle there are the eight inverters currently being tested.
On the right, there is a power transformer connecting the left breaker box to the residential (two-phase 240V) breaker box. The restdential breaker box is connected to all the inverter outlets and some test loads (fans, heaters, a microwave).
The commercial breaker panel:
Two Chroma 62000H-S Solar Array simulators:
They can act like a normal DC power supply and also simulate the effects of shadows, clouds, and a day cycle.
The power transformer taking the commercial circuit down to a two-phase 240V circuit that all the test loads and solar inverters are hooked up to:
On top there is an SEL-735 Revenue Meter to monitor the overall power that the loads are drawing from the rid+inverters. The inverters all have internal power measurement built in as well.
The inverters are:
- ABB PVI-5000
- ABB PVI-3.0
- Fronius IG Plus
- Fronius Primo
- SolarEdge SE6000
- SolarEdge SE6000A
- Schneider Electric Conext
- Delta Solivia 3.0TL
Open to any questions or requests for better images (not taken with a phone).
I'm the communications guy, so I can answer those questions easily. I can forward any electronics-related questions to my coworker.
