10.24-30.72 kWh from 2 to 6 modules
Every 5.12 kWh, 102.4 V module added to the stack raises system energy, from 10.24 kWh on two modules to 30.72 kWh on six.

A stacked high-voltage LiFePO4 cabinet built from 5.12 kWh, 102.4 V modules: two of them make 10.24 kWh, six make 30.72 kWh, at 204.8-614.4 V nominal.

The Felicity Solar FLH96050SG2 is a stacked high-voltage LiFePO4 battery built from 5.12 kWh, 102.4 V modules. Two to six modules give 10.24 to 30.72 kWh of system energy at 204.8 to 614.4 V nominal, of which 9.21 to 27.64 kWh is usable at a 90% depth of discharge. Across that 2 to 6 module range the pack operates between 185.6 V and 691.2 V. Each 50Ah module accepts 50 A maximum continuous charge and discharge current, with 25 A the recommended figure for everyday cycling, over a cycle life rated at 6000 cycles or more. A built-in smart BMS and breaker cover protection, an LED plus LCD touch display reports pack state at the cabinet, and RS485 and CAN ports carry that data out. The IP65 enclosure stacks or floor-mounts and is listed at 600 x 1760 x 385 mm and 357.5 kg, each battery module weighing 57.5 kg net and the control module 12.5 kg net (24.5 kg with its base). Charging runs 0 to +55 C, discharging -20 to +55 C, at 5% to 95% humidity below 2000 m. We are an authorised Felicity Solar distributor and supply the FLH96050SG2 from our own stock.

An off-grid house is sized by surge, battery energy and charge current - and the surge row is the one that starts your fridge and your pump. Here are the published figures across the Felicity inverters and batteries, with the arithmetic to use them.
Read: How to Run a Whole House on Solar in Khartoum →Extend your off-grid battery life with proper maintenance. Covers LiFePO4, gel, and lead-acid battery care, temperature management, and charge settings.
Read: How to Maintain Solar Batteries for Maximum Lifespan →Overcharging destroys batteries fast. Learn how to set correct charge voltages, use temperature compensation, and configure your Felicity IVPS to prevent damage.
Read: How to Protect Your Off-Grid Batteries from Overcharging →9.21 kWh with two modules and 27.64 kWh with six, because the 90% depth of discharge applies to a system energy of 10.24 to 30.72 kWh. Each battery module contributes 5.12 kWh at 102.4 V, and the stack accepts 2 to 6 of them.
357.5 kg and 600 x 1760 x 385 mm are the listed cabinet figures. Each battery module weighs 57.5 kg and measures 600 x 385 x 260 mm, and the control module is 600 x 385 x 200 mm at 24.5 kg with its base, so the lift to plan for is a module at a time.
50 A is the maximum continuous charge and discharge current, with 25 A recommended for daily cycling of the 50Ah modules. RS485 and CAN ports carry the smart BMS data, and an LED plus LCD touch display shows pack state on the cabinet.
