SOLAR KING

The most advanced grid-tie PV inverter in the world. Converting sun light into electricity energy for home / industrial applications, and powering up our world with free solar energy is now no longer just a dream.

Features :

Powercom Solar king is the most advanced solar inverter for grid connected PV-plant. Solar king is designed base on the following principles:
High converting efficiency / boosting system effeciency via MPPT / Low cost / easy installation and maintenance / user friendly / and long-life usage.

With 3 different input voltage ranges allowing customer to have flexible choice for different applications.

96.5% high converting efficiency and up to 99% high MPPT efficiency are both above average market standard.

Solar King is designed to be user friendly and with easy installation to reduce installation costs. User can easily monitor the system status from the remote control display LCD panel.

IP-65 enclosure protects against severe outdoor installation environment.

USB & RS-232 communication ports are available for remote monitoring & control. With optional RS485 or SNMP card for future expansion.

* Load curve :

The relation of input DC voltage and output power is shown in figure. Once input V is less than 250V, the relation of I/P V and load % is : Load% = 0.4 x Vi

1. This is voltage range that inverter will start to feed power to grid.
2. The DC resistance requirement for positive or negative terminal to chasis ground
