Autonomy & Pytes V5 Battery Calculator
Indicative engineering tool. This calculator helps estimate the order of magnitude of battery storage and PV power required. It does not replace a detailed electrical load study.
Autonomy calculation with Pytes V5 batteries
Enter average daily consumption and the number of autonomy days required. The indicative calculation uses a Pytes V5 module with 5.12 kWh nominal energy and a conservative design margin.
How to read the results
- Batteries: shows an indicative number of modules for the requested stored energy. Final selection also depends on permitted charge/discharge currents.
- PV power: is an approximate estimate using a general solar-yield and loss assumption. Actual production depends on location, orientation, tilt and shading.
- Inverter: cannot be sized correctly from daily kWh alone. Maximum simultaneous power and starting currents must be assessed.
Why Pytes V5
The Pytes V5 LiFePO4 5.12 kWh is an expandable 48V storage solution for compatible systems. Final compatibility, number of parallel modules, BMS communication and current limits must always be checked against the exact inverter model and equipment version.
Important when expanding a battery bank
Adding new modules should not be assumed to be possible “at any time”. Before expansion we check the age and condition of existing batteries, firmware, BMS, cabling, protection and manufacturer instructions.
