48V Hybrid Inverter + Battery Kit · 1× Inverter / 12× Battery · No Panel
This inverter-and-battery kit pairs a 12,000W NOVA 12K hybrid inverter with twelve ALPHA 5 PRO server rack batteries — 61.44kWh of storage on a 48V system — sold without solar panels for pairing with panels you already own or plan to add separately.
12,000W PV input, 10,000W continuous AC output, 120/240V split-phase, dual MPPT. RS-H12K
51.2V 100Ah (5,120Wh) each — 61.44kWh combined, rated for 7,000+ cycles. RS-B5121P
This kit does not include solar panels. It's built for pairing with an existing array or panels purchased separately — the NOVA 12K accepts up to 12,000W of PV input across its dual MPPT trackers.
10,000W continuous output at 120/240V, with dual MPPT trackers and support for solar, battery, utility, and generator input.
Twelve ALPHA 5 PRO batteries provide high-capacity energy storage and extended backup power on a 48V system.
Built-in WiFi on the inverter and Bluetooth/WiFi app monitoring on each battery keep the whole system visible from a phone.
Inverter and battery counts are pre-matched, with two battery racks included to simplify installation.

It's designed for customers who already have panels or want to select them separately. The NOVA 12K supports up to 12,000W of PV input across two MPPT trackers, so panels can be added to match your site.
61.44kWh combined from twelve 5,120Wh ALPHA 5 PRO batteries, each rated for 7,000+ deep cycles and expandable up to 30 units in parallel.
Each ALPHA 5 PRO has an integrated 150W heater that activates automatically below 41°F and shuts off once the battery warms past 50°F; charging locks out entirely below 32°F.
Yes — the NOVA 12K accepts solar, battery, utility, and generator input, with a second input power source supported for generator compatibility.
Given the scale of this system — a 12,000W hybrid inverter and a 61.44kWh battery bank — installation should be handled by a qualified, licensed electrician or solar installer familiar with your local code.
