5. Sąranka ir diegimas
The Erayak GT-800 Micro Inverter is designed for easy installation. Follow these steps for a successful setup:
- Montavimas: Securely mount the micro inverter in a suitable location, preferably in a shaded area to optimize performance. Use the provided screw sets.
- Saulės skydo jungtis: Connect up to two solar panels (250W to 550W each) to the inverter's MC4 compatible module connectors. Ensure correct polarity. The input voltage diapazonas yra 20V-50V.
- Kintamosios srovės tinklo jungtis: Connect the inverter to your AC grid using the provided 2-meter AC connection cable. The inverter supports AC Daisy Chain cabling for multiple units.
- Parallel Installation (Optional): For larger systems, multiple GT-800 inverters can be connected in parallel. Each inverter operates independently, ensuring continuous power generation even if one unit experiences an issue.

6. Operacija
The Erayak GT-800 Micro Inverter features advanced technology for optimal performance and monitoring.
6.1 MPPT technologija
The inverter utilizes Maximum Power Point Tracking (MPPT) technology to optimize the current detection of solar panels. With a CEC efficiency of 96.5%, the dual MPPT tracker ensures optimal performance by accurately capturing and converting sunlight into electricity, maximizing power output by over 25% compared to systems without MPPT.
6.2 WiFi SmartLife App Monitoring
The GT-800 allows for remote control and monitoring via the SmartLife mobile application. This application enables you to:
- Monitor electricity production efficiency in real-time.
- Track energy capture and consumption.
- Control the inverter's switching system remotely.

7. Priežiūra
Regular maintenance ensures the longevity and optimal performance of your Erayak GT-800 Micro Inverter:
- Valymas: Reguliariai valykite keitiklio išorę, kad pašalintumėte dulkes ir šiukšles. Naudokite minkštą, damp audinys. Nenaudokite stiprių cheminių medžiagų ar abrazyvinių medžiagų.
- Jungtys: Annually inspect all electrical connections (MC4 and AC) for tightness and signs of corrosion. Ensure they are secure.
- Vėdinimas: Ensure that the area around the inverter is clear to allow for proper airflow and cooling.
- Stebėjimas: Regularly check the SmartLife App for any error messages or unusual performance readings.
8. Problemų sprendimas
This section provides solutions to common issues you might encounter with your Erayak GT-800 Micro Inverter.
| Problema | Galima priežastis | Sprendimas |
|---|---|---|
| Nėra išvesties galios | No sunlight, DC input voltage too low, AC grid disconnected, inverter fault. | Check solar panel connections and sunlight conditions. Verify AC grid connection. If issue persists, contact support. |
