PECRON FP5000-48V 5,120Wh Expansion Battery for F5000LFP

PECRON FP5000-48V 5,120Wh Expansion Battery

If you already own the PECRON F5000LFP and need longer backup time, this is the correct matching expansion battery. The FP5000-48V adds another 5,120Wh of storage without adding a second inverter or a separate power station.

Important: this is an expansion battery for the PECRON F5000LFP. It is not a standalone power station and does not provide household AC outlets by itself.

Specifications

Compatibility and Installation

The FP5000-48V is specifically listed for the PECRON F5000LFP. Do not connect it to another PECRON model, a third-party inverter, or a generic 48V battery system unless PECRON provides written compatibility approval.

Turn the system off and follow PECRON’s connection order before attaching or removing an expansion battery. Keep connectors dry, fully seated, and protected from damage. Place the battery on a stable surface with the ventilation clearance required by the manufacturer. This equipment should not be exposed to flooding, standing water, or unsafe temperatures.

Frequently Asked Questions

Does this battery work by itself?

No. The FP5000-48V is an expansion battery. It requires a compatible PECRON F5000LFP power station to provide charging control and usable power outputs.

How much capacity does it add?

It adds 5,120Wh of nominal battery storage. Actual usable AC energy will be lower after inverter losses and will vary with load, temperature, system settings, and battery condition.

Is this the older 3,840Wh model?

No. The current FP5000-48V is rated at 5,120Wh. Some older URLs and search results still contain “3840Wh,” but PECRON’s current product title and listing identify this battery as 5,120Wh.

Will it increase the F5000LFP’s output wattage?

No. An expansion battery increases stored energy and runtime. The connected F5000LFP inverter determines maximum AC output.

Can I add more than one expansion battery?

PECRON advertises F5000LFP configurations with multiple FP5000-48V batteries. Follow PECRON’s current maximum-battery limit, cabling instructions, and firmware requirements before expanding the system.

How much additional runtime will I get?

Divide approximately 4,300 to 4,600 usable watt-hours by your average load for a practical estimate. For example, a steady 500W load may gain roughly 8–9 additional hours, while a 1,000W load may gain about 4–4.5 hours. Cycling appliances will vary.
