Sol-Ark SA-30K-3P 30kW Three-Phase Hybrid Inverter

Sol-Ark SA-30K-3P 30kW Three-Phase Hybrid Inverter

When your energy demands outgrow what a residential inverter can handle, it's time to step up. The Sol-Ark SA-30K-3P is built for light commercial buildings, agricultural operations, manufacturing facilities, and large properties where a 12kW unit simply isn't enough. With 30kW of continuous three-phase output and up to 39kW of solar input, this is the inverter you install when the stakes — and the loads — are serious.

One Pre-Wired Unit. Commercial-Grade Results.

Like every Sol-Ark inverter, the SA-30K-3P arrives pre-wired and ready to go. Inverter, four MPPT charge controllers, AFCI/GFCI protection, arc fault detection, rapid shutdown, lightning protection, and a color touchscreen display — all integrated into a single outdoor-rated NEMA 3R enclosure. No transformer required for most light commercial settings. No sourcing extra components. Your installer shows up, mounts it, connects it, and commissions it — that's the Sol-Ark advantage.

30kW Output. 45kVA Peak Surge.

The SA-30K-3P delivers 30,000W of continuous three-phase AC output at 120/208V with a peak surge capacity of 45,000VA for 7 seconds — more than enough headroom to start large three-phase motors, HVAC compressors, elevators, and industrial equipment without tripping or throttling. A 200A grid pass-through simplifies grid-tied and backup applications, reducing wiring complexity on larger commercial installs.

39kW of Solar Input Across Four Independent MPPTs

Four MPPT trackers accept up to 39,000W of DC solar input across a nominal voltage range of 150–500V, with a maximum input voltage of 550V and up to 36A per MPPT channel. Multiple roof sections, ground mounts, carports, or mixed-orientation arrays can each run on their own tracker — maximizing production across every part of your installation without compromise.

Outdoor-Rated. Built to Last.

The NEMA 3R enclosure means the SA-30K-3P can be installed outdoors, directly on an exterior wall or in an equipment yard, without needing a dedicated electrical room or weatherproof housing. Combined with Sol-Ark's industry-leading 10-year warranty and 7-day-a-week live engineering support, this is a unit you can count on for the long run.

Scale From 30kW to 300kW Without Replacing a Thing

The modular design allows businesses to expand solar power generation from 30kW up to 300kW to meet growing energy needs by stacking up to 10 units in parallel. Whether you're building out a commercial facility in phases or planning a microgrid from scratch, the SA-30K-3P gives you a foundation that scales without forcing a costly equipment swap down the road.

AC and DC Coupling — Use What You Already Have

The SA-30K-3P supports simultaneous DC and AC coupling, boosting PV energy without increasing the PV array size and reducing storage inverter costs by up to 30%. If you have an existing string inverter system on-site, you can AC-couple it directly into the SA-30K-3P rather than ripping everything out and starting over. That means faster retrofits, lower total project cost, and more flexibility on system design.

Cut Demand Charges. Keep the Lights On.

For commercial customers, demand charges can represent 30–50% of a monthly utility bill. The SA-30K-3P's built-in Time-of-Use scheduling and peak shaving capabilities let you draw from batteries during peak rate windows, reducing your demand exposure automatically. Up to 97.5% inverter efficiency ensures that very little of your solar production is lost in conversion, making every kilowatt-hour count toward your bottom line.

5-Millisecond Transfer. No Business Interruption.

A blazing-fast 5ms transfer time provides seamless backup power during grid outages, ensuring business continuity without the delays or dips that can crash POS systems, disrupt manufacturing lines, or reset sensitive equipment. For commercial operations where downtime is expensive, that speed matters.

High-Voltage Battery Flexibility

The SA-30K-3P accepts high-voltage battery connections across two separate battery inputs, with a combined maximum charge and discharge current of 100A (50A per input) at a nominal 300V DC. It supports both lithium-ion and lead-acid chemistries, and closed-loop BMS communication is supported for compatible lithium battery brands — giving you the storage flexibility to match your project's budget and performance requirements.

Certified and Grid-Ready Nationwide

Certified to UL 1741-2021 (including UL1741SB), CSA C22.2, IEEE 1547-2018 and amendments, and UL1699B arc fault protection, the SA-30K-3P meets interconnection requirements across U.S. utility jurisdictions including California Rule 21 and Hawaii Rule 14H. Built-in Wi-Fi and Ethernet enable real-time remote monitoring, fleet management, and firmware updates — so your team can manage dozens of sites from a single dashboard without rolling a truck.
