PCENERSYS battery 15.36 kWh 51.2V M16S300BL-V, LiFePO4

This is a "48 volt" type battery, the most widespread format for hybrid and off-grid inverters for houses, cabins and farms. It looks like a vertical metal cabinet and is connected to the inverter through two thick cables and a data cable, through which the battery constantly tells the inverter how full it is and how much current it is allowed to receive or give. On the enclosure it has a screen that shows the status, so you do not depend on a phone to see what is happening.

The 15.36 kWh mean a reserve sufficient for the evening and night consumption of a home, and if that is not enough up to 15 units can be connected in parallel, that is approximately 230 kWh, without replacing the units already installed. It can deliver 200 A continuously, that is over 10 kW, with a peak of 400 A for 3 seconds, which covers the starting of heavy loads, such as pumps and compressors. The efficiency is a minimum of 96%, the self-discharge about 2% per month, so the battery keeps its energy even if it is not used for a while, and the service life exceeds 6,000 cycles. The box measures 580 x 750 x 279 mm and 125 kg net, so it is installed by two people, on a firm floor, in a technical space protected from frost; the warranty is 5 or 10 years, depending on the version.

Grade A LiFePO4 cells in a 16S configuration, 51.2 V nominal, 300 Ah, 15.36 kWh; charging voltage 58.4 V, discharge cut-off voltage 42 V, compatible with the standard 48 V profiles. Maximum continuous current 200 A on charge and discharge, peak 400 A / 3 s. Integrated BMS with protections against overvoltage, undervoltage, overcurrent, short circuit and temperature, cell balancing and RS485 and CAN communication (the M16S series also offers RS232), compatible with the protocols of most inverters. Temperatures: 0...60 °C on charging, -20...65 °C on discharging, storage -5...40 °C. SPCC metal enclosure, paralleling up to 15 units.

Who it suits

Suitable for a house, a cabin or a farm with a 48 V hybrid inverter, where a lot of instantaneous power is needed for pumps and compressors and where the battery bank may be enlarged later.

Terms explained

• 48 V system (low voltage): The most widespread battery format for houses; it matches most hybrid and off-grid inverters on the market.
• Discharge cut-off voltage: The threshold at which the electronics stop the discharge, so that the battery is not emptied too far and damaged.
• Self-discharge: The energy lost by itself while the battery sits unused; 2% per month means a very small loss.

Technical specifications

Recommended applications

• Residential storage on 48 V (low voltage) hybrid inverters
• Off-grid systems for holiday homes, cabins and farms
• Backup for high-power loads, with starting peaks (pumps, compressors)
• Staged extension of the battery bank by paralleling several units

Warranty

5 or 10 years, depending on the version

Technical details

Specifications confirmed from the manufacturer's datasheet

PCENERSYS M16S300BL-V is a low-voltage battery with grade A LiFePO4 cells, in a configuration of 16 cells in series, with a rated voltage of 51.2 V, a capacity of 300 Ah and an energy of 15.36 kWh. The charging voltage is 58.4 V, and the discharge cut-off voltage 42 V, values compatible with the standard 48 V profiles of the usual hybrid and off-grid inverters.

The pack supports 200 A of continuous current both on charging and on discharging, that is over 10 kW, with a peak of 400 A for 3 seconds for starting inductive loads. The charge-discharge efficiency is a minimum of 96%, and the service life exceeds 6000 cycles. The self-discharge is about 2% per month.

The integrated BMS provides the protections against overvoltage, undervoltage, overcurrent, short circuit and temperature, plus cell balancing, and communicates over RS485 and CAN (the M16S series also offers RS232), being compatible with the protocols of most inverters on the market. The operating status is read on the LCD screen on the enclosure and on the LED indicators. Up to 15 units can be connected in parallel, that is up to approximately 230 kWh, with later extension without replacing the existing units.

In construction it is a vertical-type battery with an SPCC metal enclosure, 580 x 750 x 279 mm and 125 kg net. The temperature range is 0...60 degrees C on charging and -20...65 degrees C on discharging, with storage at -5...40 degrees C. The warranty is 5 or 10 years, depending on the commercial version.
