Sol-Ark power, sized for smaller 120V systems: SA-5K-1P
Why You'll Love The Sol-Ark SA-5K-1P Hybrid Inverter
Full Sol-Ark capability in a 53 lb package.Inverter, charge controller, touchscreen and remote monitoring in one wall-mounted unit that one person can hang — a fraction of the weight of Sol-Ark's whole-home models.
Far more solar than its output suggests.It accepts up to 10,400W of PV across two MPPTs, more than double its 4,800W AC output, so you can oversize the array and keep harvesting through poor light.
Grid-tied, off-grid or backup — switching in 5ms.It manages solar, battery, grid, loads and a generator together, handing over to battery in five milliseconds when the grid drops.
Your choice of batteries, charged quickly.120A of charge and discharge on a 48V bank, working with lithium or lead-acid from 50Ah to 9,900Ah, with 3-stage charging and equalization.
Your life, with the Sol-Ark SA-5K-1P Hybrid Inverter
Not every project needs a whole-home inverter. A cabin, a workshop, a small off-grid build or a partial-home backup doesn't need 15kW — it needs the same engineering in a size that actually fits.
That's what the SA-5K-1P is for. It delivers 4,800W of continuous 120V power, manages solar, batteries, grid and generator together, and hands over to battery in five milliseconds when the grid goes down.
At 53 lbs it's light enough to wall-mount without a crew, and it takes up to 10,400W of solar — more than double its own output — so an oversized array keeps producing on grey days rather than sitting idle.
One thing worth being straight about: this is a 120V single-phase unit with 50A grid pass-through. It's built for smaller systems and 120V loads rather than a whole-home 240V service. If you need to run 240V appliances, one of Sol-Ark's larger models is the right call — give us a shout and we'll point you at it.
Within that brief, there's real capability behind the small footprint.
Two MPPTs with two strings each accept up to 500V input across a 150–425V operating range, with input current self-limiting to keep array design flexible. Batteries connect on 48V with a 3-stage charging controller, equalization, and an integrated current shunt for accurate state-of-charge readings.
Generator support is built in with automatic generator start, and sell-back modes cover both household-limited and fully grid-tied operation where your utility allows it. It's IP65 / NEMA 3R rated, runs from -40°C to 60°C, sits under 30 dB and draws 60W at idle — with Wi-Fi and LAN included and a 10-year warranty as standard.
The Sol-Ark SA-5K-1P Hybrid Inverter in a nutshell:
4,800W continuous at 120V single phase— with 7,200VA of surge for 5 seconds off-grid.
Up to 10,400W of solar across 2 MPPTs— oversize the array and harvest more of the day.
120A charge and discharge on 48V— lithium or lead-acid, from 50Ah to 9,900Ah.
53 lbs, wall-mounted, IP65 / NEMA 3R— straightforward to site indoors or out.

Let the experts help you find your perfect hybrid inverter
Not sure whether the Sol-Ark SA-5K-1P suits your loads, or whether you need a larger 240V model instead? We're here to help you get that decision right before you buy.
The information on this page is provided for general guidance only and should not be taken as professional, electrical or medical advice. The Sol-Ark SA-5K-1P is a high-voltage, grid-interconnected product and must be installed by a qualified, licensed electrician in line with the manufacturer's user manual and your local codes; grid-tied, sell-back and generator-connected use may also require permits and utility approval. This is a 120V single-phase inverter with 50A grid pass-through and is not intended to back up a whole-home 240V service. Every situation is different, so if you have any doubt, please consult a qualified professional before purchasing or installing. Products are used at your own risk
