Sol-Ark SA-5K-1P 5kW String Inverter

Sol-Ark SA-5K-1P — 5kW Single-Phase All-in-One Hybrid Inverter

The Sol-Ark SA-5K-1P is a pre-wired, all-in-one hybrid inverter built for homeowners and installers who demand flexibility, reliability, and code-compliant performance out of a single compact unit. Combining an inverter, MPPT charge controller, load center, rapid shutdown, auto generator start, and Wi-Fi monitoring into one factory-wired enclosure, the SA-5K-1P eliminates the complexity of multi-component system builds and gets you to a clean, permitted install faster.

True Hybrid Operation — Grid-Tie, Off-Grid, and Backup in One

The SA-5K-1P seamlessly transitions between grid-tied, off-grid, and battery backup modes without any manual intervention. Whether you're offsetting utility costs, riding out a power outage, or running a fully independent off-grid system, this inverter keeps your home powered without missing a beat. It supports both 120V and 230V output configurations, making it one of the most versatile single-phase inverters available for U.S. residential installations.

Up to 10,400W of Solar Input with Dual MPPT

With two independent MPPT trackers and a maximum PV input of 10,400W, the SA-5K-1P lets you maximize your solar harvest across different roof orientations or shading conditions. Each MPPT channel handles up to 20A of self-limiting input current, with a PV voltage range of 150V–500V and a startup voltage of just 125V — meaning your system begins generating power earlier in the morning and later in the evening than many competing units.

Pre-Wired and Ready to Install

Unlike inverters that require separate charge controllers, combiners, and rapid shutdown equipment, the Sol-Ark SA-5K-1P ships pre-wired with everything needed for a compliant install. AFCI, GFCI, and rapid shutdown are built in, meeting NEC 2023 requirements without add-on hardware. The result is a faster installation, fewer components to wire, and a significantly reduced chance of field wiring errors.

Time-of-Use Optimization and Smart Load Management

The SA-5K-1P includes built-in Time-of-Use (TOU) programming that automatically shifts energy draw and storage based on your utility's rate schedule. Charge batteries during off-peak hours, sell back to the grid at peak pricing, and run critical loads from stored solar — all managed through the unit's LCD touchscreen with day-of-week scheduling. A programmable Smart Load Mode gives you additional control over non-essential circuits, helping you stretch every kilowatt-hour further.

AC and DC Coupling — Compatible with Existing Solar Systems

The SA-5K-1P supports both DC-coupled and AC-coupled configurations. DC coupling from solar to battery delivers maximum round-trip efficiency, while AC coupling allows integration with an existing grid-tie inverter — making this unit an ideal battery backup retrofit for homes that already have solar installed.

No Battery Brand Lock-In

Sol-Ark does not restrict you to a proprietary battery ecosystem. The SA-5K-1P works with a wide range of 48V battery chemistries including lithium iron phosphate (LiFePO4), lithium NMC, sealed lead-acid, and flooded lead-acid. Whether you're pairing with a popular lithium brand or using existing batteries you already own, the inverter communicates via CAN/RS485 with most major battery management systems.

Built-In Generator Support with Auto-Start

The SA-5K-1P includes an integrated auto generator start (AGS) function. When battery state-of-charge drops to a configurable threshold, the inverter signals a compatible generator to start automatically and charges batteries while powering loads — without any manual intervention. Generator AC input is accepted on a dedicated port, keeping generator and grid connections cleanly separated.

Remote Monitoring via Wi-Fi and LAN

Built-in Wi-Fi and LAN connectivity allow real-time system monitoring from any browser or mobile device. Track solar production, battery state, grid import/export, and load consumption from anywhere. No separate monitoring hardware or subscription is required.
