8000W 48V Off-Grid Solar Kit with 15.12kWh Lithium Batteries
Modelo: 8 kW - 15.12 kWh - 48V- Sku: TBBKITA004
- Vendor: TBB
Specifications
Product Description
The 8000W 48V Off-Grid Solar Kit with 15.12kWh Lithium Batteries is designed for permanently inhabited off-grid homes and small businesses that require high power and significant autonomy. It combines 4.76 kWp in 595 W bifacial panels, a TBB Riio Sun II 8 kW inverter-charger with MPPT 250 V/100 A, and a 15.12 kWh LFP lithium battery bank (3× ES100 II) to provide stable, safe, and scalable energy.
Main Features
- Photovoltaic generator: 8× JA Solar 595 W bifacial panels (4.76 kWp) for greater actual capture and better performance with diffuse irradiation.
- TBB Riio Sun II 8 kW, 48 V inverter-charger, with MPPT up to 250 V and 100 A solar charging, flexible switching between PV, battery, and generator/grid.
- Safe LFP storage: 3× TBB ES100 II 48 V 105 Ah = 15.12 kWh nominal; usable energy ≈13.6 kWh (90% DoD) and lifespan of >6000 cycles.
- Orderly installation: PV1-F 1×6 mm² cable (red and black) 25 m + MC4 1500 VDC connectors for basic PV field wiring.
- Scalable architecture: possibility to expand modules and add more ES100 II in parallel with BMS management via CAN/RS485.
Advantages or Benefits
- 8 kW power for demanding appliances, tools, water pumps, and efficient climate control.
- Extended autonomy at night and on cloudy days thanks to the LFP bank with high depth of discharge and low degradation.
- Higher actual production with bifacial modules compared to conventional modules, optimizing available space.
- Intelligent system management: the inverter-charger prioritizes PV, backs up with battery, and allows generator or grid support.
- Optimized total cost of ownership due to the long battery lifespan and high system efficiency.
Purpose or Applications
Permanently inhabited off-grid homes, rural accommodations, small agricultural operations, workshops, and remote offices that require continuous 230 V AC supply with medium-high demand, frequent peaks, and future expansion capability.
