Solartech self-developed PB-G3 series solar pumping inverters have the following features:

1.Compatible with submersible pumps, surface pumps, swimming pool pumps using 3-phase asynchronous motors.
2.Patented dynamic VI maximum power tracking (MPPT) algorithm, fast response, good stability and 99% MPPT efficiency.
3.Fully automatic operation. Pump operation frequency range can be set based on project requirement. 8 years storage capacity for operation data.
4.Up to 98% conversion efficiency of the inverter.
5.Support soft start of pump, full motor protections, optional water level switch to prevent overflow and dry running.
6.Good sealing, IP65 protection grade. Ambient temperature: -20℃~+60℃. Ambient humidity ≤95%. Suitable for various harsh outdoor environments.
7.Using high standard components, wide input voltage range, built-in boost circuits for low power models, flexible options for solar panels configuration.
8.LCD display, user friendly interface, abundant display information.

1. Support PV/AC power complementary input, with solar priority function selection which can meet the requirement of 24 hours application while the priority is given to the maximum utility of solar energy and the AC power supply is automatically shielded to achieved the goal of main power saving.
2.Optional built-in wireless communication module to implement system remote monitoring.
3.Support timing control, pressure detection and control, liquid level depth detection and control and other water pump control functions.
4.Support multi-linkage operation function, meet the expansion of large-flow and high-lift systems application, improve the power efficiency and reduce the configuration usage of PV modules of the system.
5.Support locking the solar pumping system through power consumption quota or timing, to realize the requirement of Pay & Go function.
