The SunGold Power 13kW 48VDC Off-Grid Solar Kit Spreads a 9900W Bifacial Array Across All Four MPPT Inputs for Around 30kWh a Day

The SunGold Power 13kW 48VDC Off-Grid Solar Kit is SunGold's SGR-13K25E package. It combines two 6500W split phase inverters, twenty-two 450W bifacial N-type panels and five 5.12kWh server rack LiFePO4 batteries in an enclosed cabinet, plus four sets of PV cables, four PV breakers, DC breakers, battery cables and Z-brackets.

SunGold says the system has the potential to produce around 30kWh per day and can meet the energy needs of most households, including heavier loads like air conditioners and well pumps. It is aimed at full-time off-grid living, with room to add batteries, panels or inverters later.


SunGold Power 13kW 48VDC Off-Grid Solar Kit Features

Four Strings on Four MPPT Inputs

SunGold's wiring diagram splits the array into four strings, two strings of five panels on one inverter and two strings of six on the other. Each string has its own 25A PV breaker and its own MPPT input, so both inputs on both inverters are in use. Each input is rated for 5000W and up to 550Vdc open circuit.

Around 30kWh of Daily Solar Potential

With 9900W of panels, SunGold rates this kit at around 30kWh per day. That gives the system solar energy for daytime loads and for recharging the 25.6kWh battery bank.

25.6kWh Cabinet Battery Bank

Five SG48100P batteries, each 51.2V 100Ah and 5.12kWh, sit in the included enclosed cabinet. Each module supports 100A continuous charge and discharge, at least 7000 cycles and a 15-year design life. SunGold lists UL1973, UL9540A, CE and UN38.3 for the batteries.

Bifacial N-Type Solar Panels

The 450W panels have a module efficiency of 22.5%, and SunGold says the rear side can harvest up to an additional 30% energy from reflected light. The dual glass build is certified for 5400 Pa snow and 2400 Pa wind loads.

13000W of Pure Sine Wave Output

Each inverter is rated at 6500W with a 13,000VA peak at 120/240Vac. Paralleled, the two supply 13000W, enough headroom for 240V pumps and air conditioning alongside household circuits.

Grid, Generator and Time-Slot Charging

A utility or generator can charge the batteries at up to 80A per inverter, with up to 140A of mixed charging. The time-slot function lets you schedule charging and discharging around local peak and off-peak rates.


Real-World Applications

Full-time off-grid homes. Cover daily household use with around 30kWh of solar potential and 25.6kWh of storage.

Homes with cooling loads. Run air conditioners and well pumps from 240V split phase output.

Homesteads and farms. Supply a house and outbuildings from one ground-mounted array.

Generator reduction. Use solar for most of the day and save a generator for long stretches of poor weather.


How It Compares to Common Alternatives

Versus one string per inverter. Layouts that use a single MPPT input per inverter leave half the inputs empty. This kit uses both inputs on each inverter, so each unit can draw on its full 5000W + 5000W PV rating.

Versus single-sided panels. Bifacial panels can add rear-side output where the back of the array sees reflected light.

Versus buying parts separately. The inverters, cabinet, batteries, panels, breakers and cables are matched in one kit with a SunGold wiring diagram.


Is This Solar Kit the Right Fit

  • Indoor equipment space. The inverters are IP20 rated for indoor use only, and the batteries are IP20 battery boxes.
  • Array space. Twenty-two panels each measure 69.37 x 44.65 x 1.38 inches and weigh 53.35 lbs.
  • Daily energy. Plan loads around SunGold's estimate of around 30kWh per day.
  • Installation. SunGold's manual calls for installation that complies with local requirements and regulations.

This may be a good fit if

  • You want around 30kWh of daily solar potential
  • You run air conditioning or a well pump
  • You want 25.6kWh of storage in a cabinet
  • You have room for a large ground or roof array

Common Questions

How Much Energy Can This Kit Produce?

SunGold says the kit has the potential to produce around 30kWh per day. Results vary with location, season and mounting.

Why Does the Kit Include Four PV Breakers?

The array is wired as four separate strings, and each string gets its own 25A PV breaker and 50-foot extension cable set.

Can I Add Another Inverter?

Yes. Up to six identical inverters can be paralleled for single phase, split phase or 208V three phase output. Each inverter needs its own PV array, and all units share one battery bank.

Do the Batteries Communicate With the Inverters?

Yes. The inverters support CAN and RS485 communication with SunGold Power batteries.
