Volta Stage 1 Old Gen | 5.12kWh Wall-Mount Lithium Battery

Volta Stage 1 Old Gen 5.12kWh Lithium Battery

The Volta Stage 1 Old Gen is a 5.12kWh wall-mount lithium battery for solar and backup power systems. It uses LiFePO₄ battery technology and provides a nominal capacity of 100Ah. Therefore, it offers reliable energy storage for homes and light commercial systems.

The battery operates at a nominal 51.2V. As a result, it suits compatible 48V inverter systems. In addition, its wall-mount design provides a clean installation in garages and dedicated solar rooms.

Volta Stage 1 Old Gen Performance

The Volta Stage 1 Old Gen provides 5.12kWh of nominal energy storage. Furthermore, it supports a maximum continuous discharge current of 100A.

This 1C discharge capability allows the battery to support demanding loads within the system limits. In addition, the battery can provide a peak discharge current of 150A for short periods.

Therefore, it can handle short power increases from compatible loads. However, installers should always size the inverter and battery system correctly.

LiFePO₄ Battery Technology

The battery uses Lithium Iron Phosphate (LiFePO₄) chemistry. This technology provides stable performance for regular solar energy storage.

In addition, the battery offers more than 6,000 cycles at 80% Depth of Discharge under the stated operating conditions. Therefore, it suits systems that charge and discharge regularly.

The battery also requires no routine maintenance. As a result, it provides a practical alternative to traditional lead-acid battery banks.

Smart Battery Management System

An integrated Battery Management System (BMS) manages important battery functions. For example, it monitors voltage, current and temperature conditions.

In addition, the BMS provides protection against over-voltage and under-voltage. It also monitors over-current, short circuits and temperature conditions.

Therefore, the BMS helps manage the battery during charging and discharging.

Communication and Inverter Integration

The battery provides CAN and RS485 communication ports. These connections allow communication with compatible inverter systems.

As a result, the inverter and battery can exchange important operating information when the correct communication protocol is available.

However, customers should confirm inverter compatibility before installation. Compatibility can depend on the inverter model, firmware and communication protocol.

Expandable Battery Storage

Users can increase total storage by connecting compatible battery units in parallel. According to the supplied specifications, the system supports up to 15 batteries in parallel.

Therefore, customers can start with a smaller battery system and expand it later. For example, additional batteries can provide longer backup time as energy requirements increase.
