The 5kWh Solar Backup: MidNite Power 48V LiFePO4 Battery (MidNiteSolar version) 5kW SRNE Hybrid Inverter ESS Kit is a pre-engineered solar battery backup system that pairs a 5.12kWh rack-mount LiFePO4 battery with a 5,000W hybrid inverter — both selected and verified for full closed-loop compatibility. Rather than sourcing and cross-referencing components individually, this ESS kit gives residential and light commercial buyers a single, pre-matched 48V energy storage solution ready for backup power, solar self-consumption, or off-grid operation.

What's included

• Midnite Power MNPowerflo5 — 5.12kWh, 51.2V, 100Ah LiFePO4 server rack battery; rack-mount form factor
• SRNE HF4850U80-H — 5,000W single-phase hybrid inverter, 120Vac pure sine wave output

Component specifications

One purchase, one verified system

Building an energy storage system from separate components means hours of cross-referencing voltage windows, charge rate tolerances, and communication protocols — with no guarantee the pieces will actually work together. This kit eliminates that entirely. The MNPowerflo5 and the SRNE HF4850U80-H share a common 48V architecture and communicate over CAN/RS485 in closed loop, so the inverter reads battery state of charge directly from the BMS and manages charge cycles automatically — no manual configuration required.

Who this kit fits

• Whole-home partial backup — powers refrigerators, lights, fans, and small appliances through a grid outage without a transfer switch overhaul
• Solar self-consumption — pair with a rooftop or ground-mount PV array to reduce daytime grid draw and store surplus energy for evening use
• Off-grid cabin or workshop — 5.12kWh of storage paired with a 5,200W PV input ceiling covers overnight power from a typical day's solar harvest
• Light commercial facility — reliable backup for critical loads: point-of-sale systems, servers, lighting, and communications equipment
• Scalable starting point — add up to 15 additional MNPowerflo5 batteries in parallel as energy needs grow, without replacing the inverter

How the system connects

The MNPowerflo5 connects to the SRNE inverter's CAN/RS485 port for closed-loop BMS communication — the inverter actively monitors state of charge and adjusts charging in real time. Solar panels feed into the inverter's single MPPT input (120–450Vdc, up to 500Vdc OCV), which charges the 48V battery bank and simultaneously supplies connected loads at 120Vac. When grid or generator power is available (90–140Vac input), the inverter uses it as a secondary charge source or pass-through for loads during low-solar periods. The 10ms transfer switch keeps connected equipment running through brief outages. Buyers will also need a battery rack enclosure, solar panels and racking, AC/DC overcurrent protection per local electrical code, 2 AWG battery cables with ring terminals, and conduit.

Why choose this solar backup kit?

Where most backup kits use generic lithium cells with short warranties, this pairing uses EVE A grade LiFePO4 cells — the same grade used in electric vehicles — backed by MidNite Solar's industry-leading 10-year warranty and rated for 6,000 cycles at 77°F. The SRNE HF4850U80-H adds real headroom: a 5,200W PV input ceiling, an 80A solar charging current, and a 10,000VA peak surge rating mean the system handles motor-start loads and large PV arrays without derating. For buyers who want a professionally matched ESS without the integration risk, this 5kWh Solar Backup kit available through A1 SolarStore is one of the few pre-verified 48V pairings at this capacity and price point.
