This page covers HV48100 and HV48300 Max.

Pytes also offers HV48100 SE and HV48300 Max SE. The calculations below do not apply to the SE models.

These calculations check voltage limits only. They do not establish compatibility. They keep the full stated battery voltage range within the HS19 and battery controller limits.

HV48100

• Modules per stack: 14 or 15 are within the product range.
• Voltage range: 665 - 870 V DC
• Nominal Capacity per stack: 71.68 - 76.8 kWh.

HV48300 Max

• Modules per stack: 15 - 17.
• Voltage range across these configurations: 672 - 979.2 V DC.
• Capacity per stack: 241.14 - 273.29 kWh.
• A stack with 14 modules can fall to 627.2 V. A stack with 18 modules can reach 1036.8 V.

Each stack has its own voltage range. The combined range above is not the range of each stack.

HV48100

• Battery module (BMU): 51.2 V nominal, 5.12 kWh, 45.5 - 58 V.
• Battery controller (BCU): 200 - 870 V working range; 5 - 15 BMUs.

HV48300 Max

• Battery module (BMU): 51.2 V nominal, 16.076 kWh, 44.8 - 57.6 V.
• Battery controller (BCU): 224 - 1497 V working range; 5 - 26 BMUs.
