Felicity Solar Batteries — Reliable Energy Storage

Felicity Solar (FelicityESS) is a manufacturer of lithium iron phosphate batteries specializing in solar power and backup energy solutions. Our battery catalog features 8 Felicity models with 48V (51.2 V) voltage and capacities ranging from 5.12 to 25 kWh. All models include a built-in BMS (Battery Management System) that monitors charging, discharging, and temperature.

How to Choose a Felicity Battery

When selecting a Felicity Solar battery, consider these key parameters:

  • Capacity (kWh) — determines your energy reserve. For a residential solar system with 15-20 kWh daily consumption, 10-15 kWh models are sufficient. For full off-grid autonomy, consider the LPBA48500 at 25 kWh.
  • Inverter compatibility — all models operate at 48 V and are compatible with most hybrid inverters. Verify your inverter accepts 48-57.6 V input range.
  • Scalability — Felicity batteries support parallel connection of up to 6 units, allowing you to expand capacity incrementally.
  • Cycle life — LiFePO4 technology delivers over 6,000 charge-discharge cycles, translating to 15+ years of service life.

Frequently Asked Questions

Which battery is better for an inverter?

For most residential hybrid inverters, choose a 48/51 V LiFePO4 battery with BMS. Check the allowed voltage, charge current and inverter communication protocol first.

How long will a 5 kWh battery last?

A 5.12 kWh block gives roughly 4.5-4.8 kWh of usable energy, depending on DOD settings. At 500 W load it is about 9 hours; at 1.5 kW load it is about 3 hours.

Are 48 V and 51.2 V LiFePO4 batteries different?

In many catalogs 48 V means the low-voltage system class. A LiFePO4 battery often has 51.2 V nominal voltage, so the battery and inverter datasheets should be checked.

Can several battery blocks be connected in parallel?

Yes, if the manufacturer allows parallel operation and the blocks share compatible BMS firmware. Charge and discharge current limits must be checked before connection.

Is a battery for solar panels different from a battery for an inverter?

The battery connects to the inverter, not directly to solar panels. For solar ESS, check hybrid inverter compatibility, usable capacity for daytime generation and BMS communication.

What do 6000 cycles mean for a LiFePO4 battery?

It is the charge-discharge cycle rating under manufacturer test conditions. DOD, operating temperature and recommended current still affect the real service life.
