Product Features
Integrated MPPT Charge Controller
Equipped with an MPPT tracker that operates within 120-430VDC, it efficiently converts solar energy into usable power, ensuring you get the most from your solar panels.
Flexible Battery Usage
It works smoothly with or without a battery. When batteries are used, it supports both lead-acid and lithium types, with an equalization charging function to extend battery life.
Configurable Power Priority
You can set solar or grid power as the priority. If solar energy is insufficient, it automatically combines grid power to keep your devices running without interruption.
Parallel Operation for Expansion
Need more power? This inverter supports parallel operation, allowing you to connect up to 6 units for a total capacity of 30kW, growing with your energy needs.
Remote Monitoring Option
With an optional WiFi/GPRS module, you can monitor the inverter’s performance anytime, anywhere via your phone or computer, keeping track of energy usage and system status.
Usage Scenarios
Daily Home Use: During the day, solar power directly runs lights, TVs, and kitchen appliances. Excess energy charges the battery. At night, the inverter uses stored battery power or switches to grid if needed.
Remote Cabins: In areas without grid, it relies on solar panels and batteries to power lights, water pumps, and small heaters, ensuring comfort year-round.
Small Farms: Powers irrigation systems and tools during the day with solar, using backups for early morning or evening tasks.
Product Quality Control
Each inverter undergoes strict testing, including checks on voltage regulation, temperature resistance, and surge handling. It meets safety standards with features like over-current protection and short-circuit prevention, ensuring safe operation.
FAQ
Q: What batteries can I use?
A: It works with lead-acid (AGM, flooded) and lithium batteries, but lithium batteries need a BMS (Battery Management System) connection.Q: Do I need a professional to install it?
A: Yes, electrical installation should be done by a qualified person to follow safety standards.Q: Can I monitor it from my phone?
A: Yes, with the optional WiFi/GPRS module, you can check status and energy data remotely.
