Question 1

Can SolarBridge PCS Module operate on both on-grid and off-grid, what voltage configurations does it support?

Accepted Answer

Yes. The GT3-135K-US supports both on-grid and off-grid operation with a 3P4W (three-phase, four-wire) output configuration, plus PE (protective earth). On-grid, it connects at 480 Vac (3W/N+PE) with a rated frequency of 60 Hz and an adjustable power factor from −1 to +1. Off-grid, it operates at 480 Vac (3P4W+PE) and supports unbalanced load capability and parallel off-grid operation, enabling microgrid and backup power deployments.  Its DC battery voltage range spans 720–1500 Vdc, with a note that operation between 720–820 Vdc is limited to grid-connected, three-phase, three-wire (480 Vac) mode. It also supports 480/208 Vac at 70 kW for flexible site configurations.

Question 2

What is the efficiency rating of the SolarBridge GT3 Golden Gate PCS Module and what technology enables it?

Accepted Answer

The GT3-135K-US achieves a maximum efficiency of 98.5%, made possible by its three-level topology — an advanced inverter architecture that reduces switching losses compared to conventional two-level designs. The unit also uses intelligent air-cooling, which allows it to operate at full 100% capacity up to 45°C without any power derating. This combination of high efficiency and thermal performance makes it well suited for commercial and industrial environments where consistent output under load and heat is critical.

Question 3

What are the physical specifications, communication options, and certifications for GT3 PCS Module?

Accepted Answer

The GT3-135K-US is a rack-mount unit measuring 740 × 800 × 270 mm and weighing 85 kg.  It features an LED display and supports three communication interfaces — CAN, RS485, and Ethernet — using Modbus TCP and CAN 2.0 protocols for integration with BMS, EMS, and third-party platforms. The unit carries an IP65 ingress protection rating, is rated for ambient temperatures from −30°C to +60°C (with derating above 45°C), operates at altitudes up to 3,000 m (with derating beyond that), and tolerates 0–100% relative humidity (non-condensing). As a U.S.-certified product from a Non-FEOC manufacturer, it meets U.S. grid standards and is eligible for IRA-related clean energy incentives.
