Product Description

Four Renogy Core 48V 50Ah self-heating lithium iron phosphate batteries combine into a 9,600Wh (9.6kWh) 48V parallel bank — serious storage for an off-grid home, cabin, or backup system, built from 51.4 lb modules one person can carry. Each battery is rated for more than 6,000 cycles per Renogy, self-heats for charging below 32°F, and is sealed to IP65.

Who This Is For

This 4-pack fits off-grid homes and cabins running daily loads through a 48V inverter, and backup-power builds that need real overnight capacity. Paired with the Renogy 48V 3500W pure sine wave solar inverter charger, the bank's 200A combined continuous discharge carries the inverter's roughly 73A full-load draw with headroom for surges and future growth.

Key Features

Four 48V 50Ah LiFePO4 batteries — 200Ah and 9,600Wh connected in parallel
More than 6,000 cycles at 80% depth of discharge and 80% end of life, per Renogy
Self-heating engages automatically for safe charging below 32°F, per Renogy
50A maximum continuous charge and discharge per battery — 200A combined
Expandable to 8 batteries in parallel for a 19.2kWh maximum bank, per Renogy
Built-in BMS protection, IP65-rated ABS housing on every module
Modular 51.4 lb batteries instead of one unliftable cabinet

Why Renogy

The Core 48V series is Renogy's modular approach to home-scale storage: add capacity battery by battery instead of committing to a monolithic unit. OffGrid Horizon is a family-owned authorized Renogy dealer, and all four batteries carry Renogy's US warranty.

Building a 48V Bank

All connections are parallel at 48V, which keeps bank design simple: no series strings, no midpoint imbalance. Per Renogy the platform scales to 8 batteries and 19.2kWh, so this 4-pack leaves a clear upgrade path. Use equal-length, equal-gauge interconnects, land the system positive and negative on opposite corners of the bank so all four batteries share current evenly, fuse the main run for your inverter, and bring every battery to a similar state of charge before first connection. At 48V, wiring stays manageable: 200A of combined discharge moves as much power as 800A would at 12V.

Warranty & Support

Per Renogy, each battery carries a 5-year prorated material and workmanship warranty in the US; register all four serial numbers after purchase. OffGrid Horizon is a family-owned authorized Renogy dealer — call (302) 496-3554 and we will help you match charge voltage and current settings to your inverter before you flip the breaker.

Shipping

At roughly 206 lb combined, this order typically ships by LTL freight on a pallet within the United States, so plan for someone to be present at delivery. Inspect all cartons before signing the delivery receipt and note any damage with the driver — concealed-damage claims are difficult after a clean signature. Contact us immediately about any shipping damage.

Frequently Asked Questions

How much usable storage is 9.6kWh?
At 80% depth of discharge — the basis of Renogy's cycle rating — the bank provides about 7.7kWh per cycle, enough to carry typical cabin refrigeration, lighting, and electronics overnight.

Can these be monitored from a phone?
Not directly — per Renogy, this model has no Bluetooth or communication port. Most owners monitor the bank through their inverter's interface or a shunt-based monitor at the busbar.

Do they charge below freezing?
Yes. Per Renogy, built-in heating pads warm the cells automatically so charging is safe below 32°F, and discharge works down to -4°F.

What inverter pairs well with this bank?
A 48V inverter charger with LiFePO4 charge settings. The 200A combined discharge supports up to roughly 9,600W at 48V, so a 3,500W unit runs well inside the bank's comfort zone.

Can I expand past four batteries?
Yes — up to 8 in parallel and 19.2kWh total per Renogy. Add identical batteries and equalize their state of charge before connecting.

How should I charge from solar?
Use a 48V-compatible solar charge controller or a hybrid inverter charger. Each battery accepts up to 50A, so this bank can take up to 200A of combined charge current.
