Sol-Ark SA-12K-2P 12kW Hybrid Inverter On/Off Grid All-In-One 48V Battery Pre-Wired

Sol-Ark SA-12K-2P 12kW Hybrid Inverter

Blackouts are becoming the new normal. When the grid fails, the Sol-Ark SA-12K-2P makes sure your home doesn't. This 12kW all-in-one hybrid inverter is one of the most capable residential and light-commercial units on the market — and at A1 SolarStore, we carry it because it flat-out delivers.

One Box. Complete Power Control.

The SA-12K-2P packs everything into a single pre-wired enclosure: inverter, dual MPPT charge controller, AFCI/GFCI protection, rapid shutdown, breakers, and a full-color touchscreen. No separate combiner boxes. No extra components to source. Just a clean, efficient install that saves your electrician time and saves you money on labor.

Built for Whole-Home Backup

With 9,000W of continuous output and a surge capacity of 16,000VA, the SA-12K-2P doesn't flinch when your AC, well pump, or refrigerator kicks on. It transitions to battery power instantly during a grid outage — no flickering, no downtime, no worrying about what stays on and what doesn't.

Maximize Every Panel on Your Roof

Two independent MPPT trackers accept up to 13,000W of solar input across a wide 175–425V range with a 500V maximum. That means panels on different roof faces, with different orientations or shading profiles, can each be optimized independently — so you're not leaving production on the table.

Works With the Battery You Already Have (or Plan to Buy)

The SA-12K-2P plays well with both lithium and lead-acid battery banks at 48V, with a continuous charge and discharge rate of 185A. Whether you're pairing it with a LiFePO4 system today or planning to upgrade storage down the road, this inverter grows with your needs — not against them.

Stop Paying Peak Rates. Start Using Power on Your Terms.

Built-in Time-of-Use scheduling lets you decide when to pull from the grid, when to draw from batteries, and when to export. Pair that with generator auto-start and smart load management, and you have a system that actively works to lower your utility bill — not just offset it.

Ready to Scale

Starting with a smaller system now? The SA-12K-2P is stackable up to 9 units (72kW total), so you're not locked into today's capacity. As your home or business grows, your system can too — without replacing the inverter you already have.

Utility-Ready Across the U.S.

Certified to UL1741SA, CA Rule 21, HECO Rule 14H, and IEEE 1547, this inverter meets utility interconnection requirements in all major U.S. markets, including California NEM 3.0. Built-in Wi-Fi and Ethernet give you real-time remote monitoring and updates from anywhere.
