Product introduction:

The solar inverter is the heart of solar power system. Inverter is an electronic device that converts direct current DC power from batteries or solar modules into alternating current AC power to operate lights, appliances or anything that normally oerates on power supplied by the utility grid. Grid-Tie, or utility intertie, solar inverters convert DC power from PV modules into AC power to be fed into the utility grid.
K-mate HESI series inverters are high efficiency & high reliable grid-tie solar inverters. Products include the model HESI-2500GT(2500W), HESI-3800GT(3800W), HESI-5000G(5000W)T, covering the power from 1000W to 5000W.

â˜Advanced Features and Performance:
1. Accurate MPPT tracking ensures maximum energy harvest under any conditions.
2. Input over-voltage and under-voltage protection, output over-current protection, over- temperature  protection and anti-islanding protection.
3. High-rated power available up to 60 centigrade ambient temperature.
4. Best-in-class efficiency to maximize solar system return on investment.
5. Minimal exterior electronic interference.
6. Equipped with galvanic Isolation AC transformer, are compatible with the different PV module technology.
7. Flexible module selection and sizing due to wide PV input MPPT tracking voltage range.

â Attractive Design
1. LCD provides instantaneous information on power level & energy production.
2. The large heat sink design enhancing cooling and increasing reliability and long-term efficiency.
3. Free PC software for remote monitoring and system troubleshooting available online.

â Easy to install
1. Light weight and versatile mounting bracket.
2. Easy access DC (photovoltaic) and AC (Utility) terminal block simplifies wiring.
3. R ed inverter enclosure allows reliable indoor and outdoor installations.
