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.

===== Use with the HS19 (650 - 1000 V DC) =====

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.
