Image: Home Use Link Diagram. This diagram illustrates different configurations for connecting the inverter to your home's electrical system, including solar panels, batteries, and the grid.
- Inverter connects to the battery pack alone (A+B+C): For anti-reverse current grid-connected power generation from batteries.
- Inverter connects to the photovoltaic panel (A+B+D): For anti-reverse current grid-connected power generation directly from solar panels.
- Inverter connects to the photovoltaic panel + solar charge controller + batteries (A+B+C+D+E): For comprehensive anti-reverse current grid-connected power generation utilizing both solar and battery storage.
Ensure all connections are secure and comply with local electrical codes. Professional installation is recommended.
Operating Instructions
The Y&H Grid Tie Inverter offers advanced features for efficient energy management.
1. Operating Modes
The inverter supports four operating modes:
- Constant Battery Power Mode
- Battery Limiting Mode
- PV Mode
- PV Limiting Mode
These modes allow flexible control over power generation and consumption, optimizing energy usage based on your specific needs.
2. Advanced MPPT Technology
The inverter incorporates advanced Maximum Power Point Tracking (MPPT) to ensure high system efficiency. MPPT efficiency is greater than 99%, maximizing the power harvested from your solar panels throughout the day.
3. Limiter Function
When equipped with an optional limiter (purchased separately), the inverter acts as a power limiter. This function ensures that only the necessary power is supplied to your loads, preventing excess energy from being fed back into the grid. This is particularly useful for avoiding unwanted grid export and potential charges.
