LSP 100K – DC-DC Retrofit Converter
Enabling Commercial Grid-Tied Solar Systems to Become Hybrid Energy Storage Solutions
Structure & Highlights
The LSP 100K is a powerful DC-to-DC retrofit converter designed to upgrade existing large-scale grid-tied solar systems—particularly in commercial and industrial (C&I) sectors—into hybrid solar + storage systems without replacing the original inverter. This device connects between the PV array, battery bank, and grid-tied inverter, allowing smooth energy flow management and battery charging directly from solar DC.
With its high power rating (up to 100kW) and advanced control logic, the LSP 100K offers flexible deployment and is compatible with both new and existing installations, enabling battery integration for peak shaving, load shifting, and backup.
Highlights:
✅Supports large PV systems up to 100kW
✅ Enables seamless solar-to-battery energy transfer
✅ Works with existing grid-tied inverters (DC-coupled)
✅ Industrial-grade, IP-rated enclosure
✅ Designed for C&I environments: factories, malls, warehouses
