Sunfid's engineering team brings over 15 years of field experience in energy storage and microgrid deployment, with hundreds of large-scale projects delivered across demanding environments worldwide. Every unit is built around A-grade LFP cells managed by a vehicle-standard BMS, wrapped in a layered safety architecture that includes active fire suppression and precision climate control.
Built for the Outdoors, Engineered for the Long Haul
IP54-rated enclosure. Dust-tight and splash-proof. Drop it in the desert, on a rooftop, or at the edge of a mining site — rain, sand, salt spray, and temperature swings from -10°C to +50°C won't compromise performance. Skip the equipment room; install it directly on-site.
6,000+ cycle LFP cells. Commercial-grade lithium iron phosphate cells rated for 80% depth of discharge. At one full cycle per day, that's 16+ years of daily operation before degradation hits 80% capacity.
Automotive-grade BMS. Cell-level monitoring of voltage, current, and temperature with six-layer protection: overcharge, over-discharge, overcurrent, over-temperature, short circuit, and reverse polarity — all handled at the cell level, not just the pack level.
Flexible Operation Modes
Run the system the way your project demands:
- Grid-tied — feed excess solar back to the grid or use grid power as backup
- Off-grid — full standalone operation for remote sites with no grid access
- Microgrid — coordinate PV, battery, diesel generator, and load in one intelligent loop
- Peak shaving — store cheap off-peak power, discharge during expensive peak hours
- Emergency backup — instant switchover when the grid drops
The built-in diesel generator interface lets you pair solar + storage + diesel for uninterrupted power supply.
When the grid fails, the system switches to diesel seamlessly — no manual intervention, no load interruption.
