SolarEdge has released new optimizers for residential solar applications with 500W DC output, maximum efficiency of 99.5% and weighted efficiency of 98.6%. Intended for commercial and industrial applications, the optimizer offers 1.4 kW of nominal DC current.
“In residential construction, the company introduces the S500A power optimizer for short series,” said SolarEdge. “This new product enables the cost-effective design of smaller roof systems with larger power modules. Due to the growing demand for higher power modules in the European market, the S500A can be used in systems with as few as six modules using a SolarEdge home short-chain three-phase inverter and a SolarEdge home single-phase wave/moderate inverter or 10 modules. using any SolarEdge three-phase inverter.
The nominal input DC power of the S500A is 500 W, the maximum efficiency is 99.5% and the weighted efficiency is 98.6%. The S500A measures 129mm x 165mm x 45mm and weighs 790g.
“For the commercial and industrial (C&I) segment, the company introduces the 2:1 S1400 power optimizer for high-income, bifacial and high-power 700-watt modules, including G12 modules,” SolarEdge said. “The increased output current allows the PV system to be designed with fewer but more efficient springs, resulting in a typical reduction of about 30 percent in DC balance of system costs.”
“Both new power optimizers incorporate SolarEdge’s multi-layered suite of security features,” the manufacturer stated. “The SafeDCTM feature enables the DC voltage of solar power systems to automatically decrease to touch-safe levels (1 V DC per module), in the event of grid failures or when the inverter is turned off. The Rapid Shutdown feature allows installers to activate SafeDCTM by flipping a switch, so that the conductors discharge to a safe voltage level in just 30 seconds.
