LuxPower SNA5000 Inverter | 5kVA 48V Solar

LuxPower SNA5000 Inverter – 5kVA 48V Solar Solution

The LuxPower SNA5000 Inverter is a 5kW/5kVA solar inverter designed for residential and compatible light-commercial solar energy systems. It combines solar PV input, 48V battery storage and AC power management in one unit.

With a rated output of 5000W / 5000VA, the inverter provides pure sine wave AC power for compatible household and business loads. In addition, it offers surge capacity of up to 10,000VA according to the supplied specifications.

The inverter also provides a 10ms switching time, making it suitable for backup-power applications where fast transfer is important.

LuxPower SNA5000 Inverter with Dual MPPT

The LuxPower SNA5000 Inverter features two MPPT solar trackers. Therefore, installers have greater flexibility when designing compatible solar-panel arrays.

The supplied specifications state a maximum recommended PV capacity of 6000W, divided as 3000W per MPPT.

The maximum PV open-circuit voltage is 480V DC, while the stated MPPT operating range is 100–385V DC.

In addition, the maximum solar charging current is 100A. The supplied specifications list maximum solar input current as 13A + 13A and maximum MPPT efficiency above 98%.

Correct PV string design remains essential. Installers should calculate panel voltage, current and string configuration before connecting the solar array.

48V Battery Support

The inverter supports a 48V / 51.2V battery class and can work with compatible lithium and lead-acid battery systems according to the supplied specifications.

The maximum stated charging voltage is 59V.

For lithium batteries, installers should confirm BMS communication compatibility with the exact battery model before commissioning the system. Battery capacity should also match the customer’s daily energy requirements and desired backup time.

Parallel Capability and Solar Expansion

The supplied specifications state that the inverter supports parallel operation. This can provide additional system-design flexibility where compatible parallel configurations are required.

However, installers should follow the applicable LuxPower installation requirements when configuring multiple units.

Residential Solar and Backup Applications

With its combination of solar input and 48V battery support, the SNA5000 can form the centre of a residential solar and backup-power system.

However, installers should calculate the property’s peak load before installation. They should also consider appliance starting currents, daily energy consumption, battery capacity and available solar generation.

Furthermore, suitable AC and DC protection, PV isolators, battery protection and correctly sized cables should form part of the complete installation.
