The Terli 25kWh energy storage system ships in three configurations — off-grid, hybrid, and on-grid — so EPC contractors can match the right solution to each site’s grid access and budget.
Off-Grid — ~$11,500 USD
PV panels and LiFePO4 batteries supply all loads with no grid connection. The battery bank covers night use and cloudy-day power without any utility dependency. The right choice for rural electrification, island grids, and remote homes.
Hybrid Solar System — ~$12,500 USD
PV, battery, and grid work together. The system draws from solar first, stores surplus in the LiFePO4 bank, sells excess to the grid, and switches to utility when solar falls short. End customers get the lowest electricity cost and full backup protection in one unit.
On-Grid — ~$5,500 USD
No battery. PV feeds loads directly and exports surplus power to the grid. The lowest entry price for markets with reliable grid supply and net metering incentives.
| Configuration | Battery | Grid Tie | Price Reference |
|---|---|---|---|
| Off-Grid | Yes (LiFePO4 or Gel) | No | ~$11,500 USD |
| Hybrid | Yes (LiFePO4) | Yes | ~$12,500 USD |
| On-Grid | No | Yes | ~$5,500 USD |
All three configurations support RS485, WIFI, GPRS, Bluetooth, and app-based real-time monitoring. Output voltage and frequency are customized per market: 110/120/220V; 50Hz or 60Hz.
Each component in this off-grid solar power system meets professional-grade performance thresholds — the specs that determine whether a project runs for 30 years or generates warranty calls.
30kW Hybrid Inverter
MPPT efficiency up to 97.6% — maximizes PV harvest across variable irradiance conditions
