Shenzhen Solartech Renewable Energy Co.,Ltd is a Chinese company that produces PV grid-connected inverters. The inverters convert DC power from solar panels into AC power for the grid. They utilize maximum power point tracking technology to optimize power output. Solartech offers inverters in models of 1000W, 2000W and 3000W that are lightweight, compact and have protections such as anti-islanding and overcurrent limiting.

Product Introduction
PV grid-connected inverter controls and adjusts the system operation. It converts the DC produced
by the solar array into AC to the grid, and adjusts the operation point in real-time according to the
variation of irradiation to realize the maximum power point tracking (MPPT).
Product Features 
 Adopting the dynamic VI MPPT method which has independent intellectual property; fast
response speed and stable operation.
 A modified anti-islanding detection method can effectively shorten the detection time whilst
keeping a high power quality, reduce the interfere to the electric nets, and suitable for a multi-
inverter system.
 Digital control with full automatic running, data storage and complete protective function.
 Save the daily operating data automatically and consult the operating data for 8 years. It is
convenient for statistics and analyzing.
 Dormancy energy - saving technologies. Saving electrical energy.
 New design of anodized aluminum case; friendly appearance; perfect cooling and shielding.
 Through optimization of the design, grid-connected inverter is adopted with free cooling
instead of fans, and then it reduces the maintenance costs.
 Light in weight, small in size, and the installation method is flexible
