256V 330AH Lithium Battery

Store solar energy for night-time use and power outages

This battery stores solar energy for essential equipment when solar production drops or the grid fails. It can be used in a compatible residential, commercial or remote-site solar system.

A practical backup example

Consider a 10-room guesthouse using about 3,000kWh per month. During an outage, its priority circuit could include reception, WiFi and CCTV, room lights and fans, refrigeration, a cycling water pump and three occupied-room air conditioners, averaging about 4.5kW while those loads are in use. For this example, we allow 20% for battery reserve and typical system losses, leaving 80% of the 84.4 kWh nameplate energy available for comparison: 84.4 kWh × 80% = 67.5kWh; 67.5kWh ÷ 4.5kW ≈ 15 hours. Your actual backup time will depend on the equipment running, battery settings, temperature and installation conditions. Send us your electricity bill or load list and we will calculate the system around your property.

Why we also ask for your load list: Your monthly kWh shows overall energy use, while backup time depends on which appliances you want to keep running together.

Where it fits

• Solar storage for guesthouses, offices, farms, clinics and commercial backup systems
• Backup for lighting, refrigeration, communications, security and other priority loads
• Systems designed to reduce generator runtime and improve energy availability

Key benefits

• 84.4 kWh of nameplate storage for evening use and outages
• ≥6000 published cycle life
• 120A published maximum discharge current
• 1630*840*675 (mm) published cabinet size for installation planning
• 256V DC platform for matching with a compatible inverter

Check compatibility before ordering

The inverter must support the battery voltage, charging limits and communication method. If more capacity is required, confirm the manufacturer's permitted parallel or cluster configuration rather than assuming batteries can simply be added together.
