Frequently Asked Questions

Start with the appliances that must work during an outage, their power draw, and the desired backup time. The calculator can help with a first estimate, while final selection should also account for inverter limits, peak loads, and usage scenario.

Yes, but the configuration depends on available space, ventilation requirements, inverter choice, and connection method. Compact installation and correct power sizing are usually the key points for apartments.

Many Pytes models support scaling, but expansion should account for battery compatibility, inverter limits, cabling, and BMS settings. It is best to plan future expansion during the initial design.

Pytes batteries are compatible with many popular hybrid and off-grid inverters. Before purchase, check the exact battery model, communication protocol, firmware version, and current limits.

We recommend installation by a qualified specialist. Battery systems operate with high currents, so protection devices, cables, inverter settings, and safe equipment placement matter.

Yes. Pytes batteries can be used in solar power systems if the inverter and wiring scheme support PV charging and operation with the selected battery type.

Service life depends on the model, depth of discharge, temperature, charge and discharge currents, and usage profile. LiFePO4 technology usually offers a much longer cycle life than lead-acid batteries.

Yes, but the temperature range of the exact model must be considered. For cold spaces, installation conditions, charging mode, and optional heating features are important.

Do not bypass protections without understanding the cause. Record the error code, inverter model, battery model, and operating mode, then contact technical support.

Yes, officially supplied products are covered by manufacturer warranty. Terms depend on the model, purchase date, correct installation, and proper operation.

Yes. We can help with preliminary sizing, battery selection, inverter compatibility checks, and a basic configuration for your scenario.

It helps to know the installation site, critical loads, desired backup time, existing inverter model, whether solar panels are present, and space constraints.
