Yes — the inverter supports up to 5,500W of solar input in total, well above the 2,220W (6×370W) included in this kit, leaving significant room to expand.
Yes — up to 6 identical SPH5048P inverters can run in parallel in single-phase (120VAC), split-phase (240VAC), or three-phase (208V) configurations.
10.24kWh combined from two 5,120Wh LiFePO₄ batteries, each rated for at least 7,000 cycles to 80% depth of discharge — a 15-year design life per the manufacturer.
Per the manufacturer's own product description, the SGR-5KE offers a larger-capacity option with 415W panels for expanded energy needs — this kit uses 370W panels and is positioned as the smaller of the two.
Given the voltages, currents, and battery wiring involved, installation should be handled by a qualified, licensed electrician familiar with your local code.
Easy installation, works flawlessly. When i had questions on install their customer service was excellent.

We have an 5KW 48V all-in-one controller inverter from Sungold Power, and are extremely happy with this unit. Day after day it performs flawlessly, truly set-it and forget-it unit. We are in a rural area of New Mexico with no access to utility company power and are completely dependent on solar power.
When we got the unit, we were very impressed with the overall design, finish and packaging. The manual included with the unit was easy to follow and get the unit setup. We followed the easy to use instructions and had the unit up and running in no time. Sun Gold Power was the right choice and we will not hesitate to add more Sun Gold products And units as the need arises.

I purchased a 5KW 48V Solar Inverter from Sun Gold Power last year, its the center piece of a temporary power system in case we get a repeat of Helene. I didn't include my solar panels here, but the Inverter has been a big comfort through the winter, and Sun Gold Power is a name I trust to order these sorts of things from in the future for the quality of packaging and timeliness in shipping.
In terms of other hindsight, with as well as this one works, I'm thinking of getting a larger 240v outputting inverter, because this works very well, and its very easy to wire in. Its easy to add solar in and connect my panels to charge it that though that does take a little longer.

I’ve been using this 5kW 48V inverter for a while now and overall I’m very satisfied with its performance. The unit provides stable and clean power, which is important for running sensitive electronics like TVs and appliances without any issues. Installation was straightforward, and it integrates well with my battery setup.
One thing I appreciate is how consistent it is under load, handling multiple devices smoothly. The build quality feels solid, and so far it has been reliable in daily use.
Overall, a great option if you’re looking for a dependable solar inverter for home backup systems.

Really like this kit a lot! This kit has brought so much convenience to my cabin! At first I thought it would be very difficult to install this kit, but SunGold's customer service was excellent! They provided wiring diagrams and responded to my emails every day to answer my questions and helped me get the inverter communicating successfully with the batteries, and I was able to monitor the kit's operation at all times on the mobile app.
