KStar unveils battery inverter solution for C&I applications – pv magazine International


KStar’s new all-in-one power storage system for business and industrial (C&I) purposes encompasses a 5.12 kWh lithium iron phosphate (LFP) battery system with a 50 kW inverter. It contains two clusters of batteries with 10 modules every, for a most capability of 102.4 kWh.

KStar has launched a brand new all-in-one power storage system with an inverter and battery module. It’s designed for business and industrial (C&I) purposes.

The China-based storage and inverter producer stated the 5.12 kWh, 512 V batteries include lithium iron phosphate (LFP) battery cells from CATL. It contains two clusters of batteries related in parallel with 10 modules every in what KStar calls a “1 + 1 redundancy” design.

“If one battery cluster fails, the opposite 52.1 kWh battery cluster can nonetheless function usually,” KStar stated in a press release. “They function a backup to one another, the 1 + 1 redundancy design ensures the soundness of the system operation.”

The system capability may be expanded to 1 MW/2 MWh, in response to KStar. The batteries match into an exterior cupboard that measures 1,100 mm x 1,1000 mm x 2,380 mm and weighs 1.5 tons. It has IP54 safety and operates in temperatures from -30 C to 50 C. The utmost working altitude is 4,000 meters, with derating beginning at 3,000 meters.

The system is reported to “allow energy era to revive a steady energy grid, optimize the ability output curve, scale back photo voltaic curtailment, improve the proportion of renewable power in whole energy era, and optimizing the power construction,” the producer stated.

The inverter has a 50 kW energy output. It has three most energy level monitoring (MPPTs) with an enter voltage vary of 350 V to 800 V. It has an effectivity ranking of 97.5% and the utmost PV enter voltage is 1,000 V.

The transformerless inverter measures 650 mm x 715 mm x 325 mm and weighs 75 kg. It has an IP65 ranking and has clever air cooling. It operates at temperatures from -25 C to 60 C.

The brand new resolution is pre-installed on the manufacturing unit for straightforward on-site set up. It has a double fireplace suppression design.
