1. ആമുഖം
The Y&H 300W Grid Tie Micro Inverter is a compact unit designed to convert direct current (DC) power from solar panels directly into alternating current (AC) power. This AC power can then be used to supply household appliances and connect to the electrical grid. The inverter's AC output is synchronized and in phase with the utility grid, ensuring seamless integration.
This inverter utilizes Maximum Power Point Tracking (MPPT) technology, achieving an efficiency of over 98%. The peak conversion rate is approximately 80%. When calculating the required solar panel power, consider an approximate 80% conversion rate for both the solar panel and the inverter. For example, to achieve 150W output from the inverter, connect it to a solar panel of approximately 234W (234W * 0.8 * 0.8 = 149W). The solar panel power must not exceed 300W.
2 സുരക്ഷാ വിവരങ്ങൾ

- യോഗ്യതയുള്ള ഉദ്യോഗസ്ഥർ ഇൻസ്റ്റാളേഷൻ നടത്തണം.
- Ensure the solar panel's Vmp (voltage at maximum power) is within the MPPT range of 24-40V for optimal efficiency. Using 12V panels or operating in low sunlight conditions (below 18V) can lead to unstable inverter operation and potential damage.
- The solar panel power connected to this inverter must not exceed 300W.
- This Micro Grid Tie Inverter is not designed to work with batteries.
- The inverter generates heat during operation. Its aluminum alloy casing is designed for heat dissipation. It features overheat protection, which will automatically reduce output or stop operation if temperatures become too high. The unit will restart after cooling.
- Install the inverter in a well-ventilated, dry, and cool location to prevent overheating and ensure longevity.

- നേരിട്ടുള്ള സൂര്യപ്രകാശം ഒഴിവാക്കുക: Install the inverter in a shaded area to prevent excessive temperatures.
- മഴ ഒഴിവാക്കുക: Ensure the installation location protects the inverter from rain or any other liquid exposure.
- വായുസഞ്ചാരം ഉറപ്പാക്കുക: The inverter requires a well-ventilated environment to facilitate proper heat dissipation.
Image: Comparison of improper and proper inverter installation positions.
Proper Installation Position: Install the inverter underneath the PV panel where it will not be exposed to water seepage, dripping, or direct sunlight. Improper installation in an open space with water seepage and dripping, exposed to the sun, will void the warranty.
5.4 കണക്ഷൻ ഘട്ടങ്ങൾ
A simplified connection diagram is provided below for reference.

- Connect the DC output cables from your solar panel(s) to the PV input connectors on the micro inverter. Ensure correct polarity.
- Connect the AC output cable from the micro inverter to the provided 30CM AC cable.
- Plug the AC cable into a standard electrical outlet in your home, connecting it to the utility grid.
- Verify all connections are secure before powering on the system.
6. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
Once properly installed and connected, the Y&H 300W Grid Tie Micro Inverter will automatically begin converting DC power from your solar panels into AC power and feeding it into your home's electrical grid. The inverter's status indicator light will provide feedback on its operation.
