The 10kWh Home Backup System: MidNite Power 48V LiFePO4 Battery (MidNiteSolar version) 10kW MidNite Hybrid Inverter ESS Kit is a pre-engineered solar battery backup system that pairs two 5.12kWh rack-mount LiFePO4 battery with a 10,000W 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

• 2 × MidNite Power MNPowerflo5 — 5.12kWh each, 10.24kWh total
• MidNite Power MN15-12KW-AIO — 10,000W / 11.4kW with PV, split-phase 120/240Vac

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. Two MNPowerflo5 units and the MN15-12KW-AIO 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 — 10.24kWh 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 two MNPowerflo5 units communicate with the MN15-12KW-AIO via CAN/RS485 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 3 MPPT inputs (600Vdc OCV, up to 15kW PV), which charges the 48V battery bank and simultaneously supplies connected loads at split-phase 120/240Vac. 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, AC/DC overcurrent protection per local electrical code, 4/0 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 Power's industry-leading 10-year warranty and rated for 6,000 cycles at 77°F. The MN15-12KW-AIO adds real headroom: 3 MPPT inputs up to 600Vdc (most AIOs cap at 500V), built-in programmable load shedding saving $4,000–$8,000 over external solutions, 20,000VA peak surge, and 100% duty-cycle CBI magnetic hydraulic breakers throughout (vs. thermal breakers in competing AIOs derated to 80%).. For buyers who want a professionally matched ESS without the integration risk, this 10kWh Home Backup kit available through A1 SolarStore is one of the few pre-verified 48V pairings at this capacity and price point.
