10kWh Home Backup System: Discover Energy 48V LiFePO4 Battery + 5kW SRNE Hybrid Inverter - ESS kit

This kit includes the primary components listed below. Additional wiring, mounting hardware, or balance-of-system equipment may be required depending on your installation requirements. Contact our team for a personalized equipment review and custom add-on pricing.

The 10kWh Solar Backup ESS Kit combines two Discover Energy 48-48-5120-H AES Rackmount LiFePO4 batteries, the SRNE HF4850U80-H 5kW hybrid inverter, and two factory-matched cable sets into a complete solar battery backup system for home and residential off-grid installations. Every component is pre-selected for electrical and communication compatibility — eliminating the hours of datasheet cross-referencing that comes with building a system from individual parts.

What's included

• 2 x Discover Energy 48-48-5120-H — 10.24 kWh total, 51.2V, 200 Ah LiFePO4 AES Rackmount battery; 19-inch 3U rackmount form factor; GEN-4 BMS with LYNK port
• SRNE HF4850U80-H — 5,000W single-phase hybrid inverter; 120Vac pure sine wave output; built-in MPPT solar charge controller
• Discover Energy 950-0074 — AES Rackmount ESS battery cable set with terminal connectors; pre-assembled for this battery-inverter combination
• Discover Energy 950-0068 — 2/0 AWG Battery Parallel Cable Set (Positive/Negative); enables parallel connection between battery modules.

Component specifications

One purchase, no sourcing overhead

Building a home solar battery storage system independently means confirming that battery voltage, BMS communication protocol, inverter charge settings, and cable ampacity all align — typically requiring hours of datasheet review and vendor back-and-forth. This kit removes that burden: the Discover 48V LiFePO4 battery, SRNE 5kW inverter, and interconnect cable set are bundled because they are confirmed as electrically and communicatively compatible, requiring no custom configuration to establish power delivery or BMS communication.

Who this kit is for

• Whole-home backup for small to mid-size homes — 5kW of continuous inverter output supports essential loads including refrigeration, lighting, fans, and multiple small appliances simultaneously during grid outages.
• Tesla Powerwall alternative seekers — buyers who want a UL-certified LiFePO4 battery with a 10-year warranty and 100% usable capacity, without proprietary ecosystem lock-in or installer-only configuration.
• Residential off-grid solar installations — appropriately sized for cabins, ADUs, and smaller homes pairing a 3–5kW PV array with local storage for around-the-clock energy independence.
• Emergency preparedness — the 10ms inverter transfer time and 10.24 kWh of fully usable storage sustain critical loads through extended outages without a generator.
• Multi-battery system starting point — the LYNK port and parallel scaling capability (up to 184 kWh per gateway) make this kit a practical first module in a larger whole-home battery backup system.

How the components connect

The Discover 48-48-5120-H batteries connect in parallel via the 950-0068 cable set and to the SRNE HF4850U80-H inverter via the included 950-0074 cable set using Amphenol SurLok Plus terminals. The SRNE inverter manages PV charging (up to 80A MPPT), grid or generator charging (up to 40A), and AC load output simultaneously. The battery's GEN-4 BMS communicates state of charge, temperature, and cell balance data over the LYNK port, while the SRNE's RS485/CAN interface enables closed-loop charge management when paired with Discover's optional LYNK II Gateway.

Items you will likely need to complete the installation: a DC breaker or fuse between battery and inverter, an AC load center or breaker panel, PV array with appropriate string wiring, conduit, and an optional rackmount enclosure such as the Discover AES Slimline.

Why choose this solar ESS kit?

Sourcing a 5kW inverter and a 10kWh LiFePO4 battery independently typically means verifying communication protocol compatibility, matching charge parameters, and sizing interconnect cables — all before a single wire is run. This kit bundles components that are factory-confirmed compatible, backed by a 10-year Discover battery warranty and dual UL certifications across both main units. For homeowners comparing residential solar battery backup systems or evaluating off-grid storage options, it offers a credentialed, pre-engineered path to installation without the research overhead of assembling a system from scratch.
