## Description

The SUNGOLDPOWER 15000W pure sine wave inverter has peak power 45000w for 20 second.It is strong enough for big A/C and pump,or other heavy loads and many home appliances such as fridge, washing machine, oven, heater,etc. It works smoothly with external MPPT and make full use of your solar panels. It is widely used in off-grid systems for cottages, farms, car parks or farm buildings. The 15KW 48V inverter require 240Vac input and provide 110/120VAC OR 220/230/240VAC output split phase for all kinds of appliances both for 240V loads and 120V loads.

Review: Great Inverter - This is my second 6000w inverter powering my whole house off grid system. Now I go between one and another. My home has three pumps for well and septic and these inverters can handle all of them as well as everything in the home all at once. These sungold inverters work great. I highly recommend!!!
Review: Awesome Product, Awesome Support, Awesome Features - I have four of these split-phase inverters and am very pleased. The inverter is a heavy beast but that's because the internal components are heavy duty and robust. There was a problem with a cooling fan broken during shipping but SGP was quick to send a replacement without hassle. Recommend using both legs for a 240v/6000w output as each leg is 120v/3000w. This handles high demand pumps and electrical without any hiccups. The features and settings for the inverter are flexible that can use grid power, then switch to battery, or it can autostart a generator when batteries are too low and it charges the batteries. It has power settings for idle load or no load standby that simply waits for a load demand. These do get hot, but I have other inverters and equipment that get hot also and recommend additional cooling in an enclosed room. I hope to have great updates while these inverters are run continuously over the coming years.

## Questions & Answers

**Q: can we connect 15000watts of solar panels directly to the unit, into PV? if panels are giving 100v and 150amps**
A: Dear Customer, this inverter can accept 70-100V and more than 2400W solar panel, 15000W is a waste for this inverter, it's ok if it's more than 2400w, or you could have external controller according to your solar panel, thanks.

**Q: is posible to ad exstra solar charger to run more solar panels tan 40 amps**
A: You misunderstood, the solar input is 60-145v not amps!

**Q: I have a step up transformer which can take 110 and make it 220; will this take the transformed voltage current for charging a battery bank**
A: If only the ac 220v input is stable, then you can take the transformed voltage current for charging battery bank.

**Q: What size circuit breaker should I use from shore power to AC input power?**
A: Generally speaking, the shore power(load center on house or generator) you will need a 50 amp double pole breaker.... (black wire) phase A,  (red wire) phase B. You will also need a return, (white wire) and a (green wire), earth ground.  If your still not comfortable doing this, consider hiring a certified electrician.

### ⭐ AC Power Just Stopped
*by E***A on May 18, 2022*

This is an early review but here is what I know this far. The unit is heavy but feels well built. Instructions are written in a tiny font and lack plain language and examples of various setups. If connecting solar panels you need a charge controller. The charger in the unit is only for AC power to charge backup batteries, not to bring solar in or moderate DC power. You will connect the solar panel to the charge controller and the charge controller to the batteries. Add a second cable to the +/- from the battery to the DC posts on the Sun Power unit. There are no 3 prong outlets so plan to wire a breaker panel or gang box directly to the AC output wire ports. The max wire that fits in the AC port is 4 AWG. You can connect two hot lines from the inverter into the panel plus a neutral. You can wire an AC input and use it to charge batteries but it does not have a solar charge controller so budget for one. Set the dip switches per the manual. The power saver mode should be avoided during testing. You will likely need to make cables so buy the tools, cable and connectors. Buy 1 pos and 1 neg bus bar, kill switches (net line) and breaker or fuse for positive line for each section of the circuit. ****Update**** After assembling in my garage and testing, the unit stopped working. I moved the setup to my farm and set it up again and it worked for a short period. It stopped working for no apparent reason. I had power coming to the DC connections but there was no AC power coming out. The LED panel was on but there was no information to help me troubleshoot the issue so I was forced to pull it and mail it back. Returning it was a huge waste of time and their money. I didn’t want to return it but I had to when I called Sun for support and didn’t get a return call. I would think Sun would want to help customers troubleshoot issues to avoid very expensive returns of an 80 lbs item. As soon as I get a credit for the return I will be buying another inverter which will be 2-3 times as expensive to get similar specs but reliable performance and service. I wish Sun had reliable support to avoid these returns but they opt to deal with returns instead.
