Description
All-in-One Integrated Design
The Sunlight Series integrates PCS, MPPT, EMS, PCM, STS switch-over, AC/DC distribution, diesel generator control and surge protection into a single cabinet.
The advanced string-architecture with decentralized fault tolerance allows each PCS module to be independently disconnected without affecting overall system operation.
Battery clusters connect independently — no DC combiner box required.
Built for Demanding Environments
Engineered for remote mining camps, off-grid islands, oil fields, emergency construction sites, and commercial & industrial parks.
Transforms unreliable utility feeders or isolated power sources into stable, economical and green microgrids.
Supports PV, storage batteries, diesel generators and grid multi-source coupling.
Product Advantages
Why the Sunlight Series stands out in the energy storage market
IP54 (outdoor) / IP20 (indoor) protection. Over-voltage, over-current, thermal, short-circuit and EMC protection. Operating temperature -30°C to +60°C.
Charging efficiency exceeding 99.3%. Multi-string independent MPPT with up to 4 channels, max input current 200 A per channel, PV power up to 120 kW per string.
Built-in EMS for PV-storage-diesel microgrids. Supports peak shaving, self-consumption, anti-reverse flow, SOC balancing, diesel hybrid, cloud monitoring and OTA.
Supports up to 3 units in parallel for capacity expansion. String-architecture design — single module fault does not affect whole system. All-in-one deployment — plug-and-play.
