OFF-GRID POWER & ENERGY STORAGE
High-capacity storage for your indoor power system.
One floor-standing NEXUS 2 battery provides 16.08kWh of stored energy at 51.2V. Pair this 314Ah LiFePO4 battery with a compatible 48V inverter for an indoor off-grid or backup installation.

Capability that matters to your project
Storage capacity you can plan around
1 × 16.08kWh provides 16.08kWh of published stored energy. Actual usable energy and runtime depend on reserve settings, load, temperature and conversion losses.
Indoor floor-standing design
Plan an accessible utility area with a level base, service clearances and a safe handling route. Each battery weighs approximately 315 lb.
Battery communications
RS485 and CAN interfaces support communication with compatible inverters. Confirm cable pinout, battery protocol and firmware before commissioning.
What’s included
- 1 × NEXUS 2 battery
Confirm the exact accessory packing list with Torven Power. Images illustrate the configuration; loose cables, communications accessories and mounting hardware are included only when itemized for the order.
Plan the installation
Solar panels, array racking, installation labor and permits are selected separately. Your installer must specify conductors, disconnects, grounding, overcurrent protection and any required transfer equipment. Match battery discharge capability and charging limits to the inverter settings.
Frequently asked questions
How long will this battery bank run my loads?
Dividing 16.08kWh by a constant 1kW load gives 16.08 hours before reserve and conversion losses. This is a sizing illustration, not a runtime promise. Actual usable energy depends on settings and operating conditions.
Are solar panels included?
No. Select panels, racking and site-specific electrical equipment separately.
What warranty applies?
The NEXUS 2 battery has a 12-year limited manufacturer warranty. Registration, installation and exclusions follow the current written manufacturer terms.
