Wiring This System Takes Minutes

01

Turn the battery and its built-in breaker off first. Use two 2 AWG cables, 2 ft each: red from battery + to BAT+, black from battery − to BAT−. The SunGold uses ring lugs on bolt studs: lug over the stud, washer, nut, tighten. Tug each cable. If it turns or moves, tighten again.

02

The appliance cord goes to AC IN and the outlet box goes to AC OUT. Black goes to L, white to N and green to ground. Crimp a ferrule on every stranded wire first. The solar cable lands on PV+ and PV− through the PV disconnect, with the disconnect off.

Crimp Ferrules on Stranded Wire

The AC terminals on this inverter are screw clamps. When a screw lands on bare stranded wire it spreads the strands apart, some miss the clamp, and the connection can loosen and heat up over time. A ferrule turns the strands into one solid pin the clamp can grip. Use one on every stranded wire that goes into a screw terminal: the AC input cord, the AC output wires, the 6 AWG THHN to the outlet box and the two PV wires at the PV input. The kit is in Step 04 above.

01

Strip to the barrel length. Pick the ferrule that matches your wire gauge (the kit lid lists the sizes). Strip the insulation back to the length of the ferrule’s metal barrel without nicking or cutting any strands.

02

Twist and insert. Give the strands a light twist so none stick out, then push the wire in until the insulation seats inside the plastic collar. The copper should end flush with the end of the barrel.

03

Crimp it. Set the barrel in the crimper’s hex die and squeeze until the ratchet releases. The hex crimp packs every strand into one solid pin.

04

Land it in the terminal. Push the crimped ferrule all the way into the inverter’s AC terminal and tighten the screw. Tug on the wire. If it moves, tighten again.

Connect Loads With an Outlet Box

Instead of adding a load panel, breakers, Romex and outlets, use this box. It has its own breakers and NEMA 5-20 outlets. Connect it to the inverter’s AC OUT with 6 AWG THHN from any hardware store, or buy the THHN kit here.

Outlet Box to Attach Loads

Breakers and outlets in one box. About $90.

Settings to Change After First Startup

Start it in this order: battery breaker on, Cubix 100 on, inverter rocker switch on, set the menu items below, then the PV disconnect and the AC input. Turn loads on one at a time. Shut down in reverse.

You do not need a communication cable. Set the inverter by voltage instead. These are starting values for a 51.2V, 16-cell lithium battery like the Cubix 100.

ItemWhat it isSet it to
08Battery type. Default is GEL.USER
09Boost (bulk) charge voltage.56.0V
11Float charge voltage.54.0V
16Equalization. Default is on, at 58V.DIS. Never equalize a lithium battery.
12Low voltage cutoff. The inverter turns its output off here.48.0V
14Low battery alarm.50.0V
15Discharge limit voltage.46.0V
35Voltage where the output comes back on after a cutoff.52.0V (default)
28Charging current from the wall.20A or less on a household outlet. 20A of charging pulls about 10A from the wall.
63Neutral to ground bond. Default is off.ENA. See the next section.

Optional: if you plug in the communication cable, set 08 to LFP16, 32 to 485 and 33 to PYL. The battery then reports its own limits to the inverter.

Turn On the Neutral to Ground Bond

In a house, neutral and ground are tied together at the main panel. That bond is what lets a breaker trip when a hot wire touches a metal case.

This system runs on its own, so it needs its own bond. The inverter can make it, but the setting ships turned off.

  1. Open the inverter menu and go to item 63, N-G automatically connect.
  2. Change it from DIS to ENA.
  3. Plug an outlet tester into the outlet box while running on battery. It should read correct, not open ground.

With item 63 on, the inverter switches the bond automatically. Also run the green ground wires as shown in the wiring cards above.

Run 12V Loads With a 48V to 12V Converter

These golf cart converters have a 48V input, and a 12V output. The 12V output in the picture above is connected to a 12V fuse block to add loads. You can find a converter for any size you wish.

48V to 12V Converter

48V in, 12V out. Feeds a 12V fuse block.

Add an MC4 Extension Set to Connect Solar Panels

This is the proper configuration for connection

Recommended Solar Panel Array

The biggest difference from a 12V system is the solar string voltage. This inverter needs at least 120V at the PV input to charge, so the panels go in series.

Put at least 5 panels in series. 5 to 8 is the range I recommend for 400W panels. With the SunGold 590W panels from my standard panels page, use 4 to 8:

PanelsArrayVmpVoc at 77°FVoc at −22°F
42,360W178V209V242V
52,950W222V262V302V
63,540W266V314V362V
74,130W311V366V423V
84,720W355V419V483V

One string only: the inverter has one PV input rated 22A and takes up to 5,500W. Never exceed 500V at the PV input on the coldest morning. The planner at the top checks any panel.

Check Your String Voltage on the Forum

The DIY Solar Forum has a free System check under the Equipment tab. It tells you if your exact panels work with this inverter.

  1. Open the forum, click Equipment, then System check.
  2. Step 1: search for your panel and press Use. If its numbers are missing, open Edit figures and type the Voc and Vmp from the panel label.
  3. Set Panels in a row (series) to the number you plan to wire, and enter your coldest morning temperature.
  4. Step 3: search SPH5048P and press Use.
  5. Read All checks. Cold-morning voltage has to stay under 500V. Hot-afternoon voltage has to stay over 120V. Both need a green check.

Charge From Small or Low-Voltage Panels

36V/48V Rover Boost 10A MPPT Solar Charge Controller

Add an MC4 Extension Set to Connect Solar Panels

This is the proper configuration for connection

I charge my golf cart’s 48V battery from a 50W solar panel with a boost MPPT charge controller. It raises a low-voltage panel up to the battery voltage.

It fits RV and van roofs with room for only a panel or two. If you have space, higher-voltage panels in series are the cheaper route: get the string above 120V and the inverter charges from them directly.

Charge From a Vehicle Alternator

You need a dedicated, externally regulated 48V alternator. A stock vehicle charging system is not built to charge a large, deeply discharged battery. Overland and van build shops install these. I do not have a specific model to recommend yet.

Regulated 48V Alternator

If It Does Not Start

The fault codes come from the inverter manual.

Questions Before You Build

Can it run 240V loads?

No. The SunGold 5000W puts out 120V only. A well pump, dryer or range that needs 240V needs a split-phase inverter, like the ones in my off-grid system builder.

What is the biggest load it can run?

5,000W continuous, the SunGold inverter's rating. For long battery life keep steady loads under about 2,200W, the battery's recommended 50A. The inverter surges to 10,000VA for motor starts.

Can I charge it from a wall outlet or a generator?

Yes, through the AC input cord. On a household outlet set menu 28 to 20A, which charges at about 1,100W and pulls about 10A from the wall: empty to full in about 4.7 hours. On a generator, set 28 to 40A for about 2,200W, about 2.3 hours. Use a generator rated above that.

Can I use it in an RV or van?

Yes. Strap the hand truck down so it cannot move. Plug the AC input cord into shore power to pass power through and charge the battery. With menu 63 set to ENA, the inverter switches the neutral-ground bond on its own when shore power comes and goes.

Can I use a different 48V battery?

Any 51.2V, 16-cell server rack battery works with the voltage settings on this page. Check that its continuous current rating covers the loads you plan to run. Size the cables to it, and add a DC breaker if the battery does not have one built in.

Where can it sit?

Indoors or under cover, somewhere dry. The inverter runs from 14°F to 131°F and needs 8 in (200 mm) clear at its left and right vents. Keep it out of rain.

How heavy is it?

About 132 lb of gear (103 lb battery, 28.7 lb inverter) plus the hand truck. Tip it back and roll it.
