17 grid-tie inverters that do not feed into the grid | 2021
What is PV Grid Tie Inverters?
Solar panels generate direct current (DC) which is not suitable for home as well as industrial purpose.
PV grid-tie inverter converts direct current (DC) generated from PV panels into alternating currents (AC) in synchronization with gird power.
In simple words, PV gird inverter convert DC power into AC power and inject AC power into the Gird.
Grid-tie inverter that does not feed into the grid
On-gird (gird-tie/gird connected) solar power (PV) plant generates excess power when the connected load is lesser than the power generated by the solar power plant (Power generation > Power required).
This excess power is synchronized with grid power hence it can revere the power flow.
In simple words, power will flow from the PV plant owner’s home to the connected grid [when Solar power generation > Power required by connected load].
With ZED Advance gird tie inverters can be programmed to restrict the excess power generation.
ZED Advance is a programmable controller with set points, which can detect reverse power flow (from home to the grid) and control the power generation of the solar power plant.
When ZED Advance detects reveres power [solar power generation > Load demand] it ramps down the power generation of the grid-connected PV plant.
To match, load demand = solar power generation
