LFP inverter charger is used widely in off-grid solar systems. you can charge the battery directly from the solar panel by solar controller, and then provide AC power for household appliances. In addition, you can use generators or utility power to charge the battery. This provides a very flexible combination for your home or RV power system, reducing cost effectiveness by using renewable clean energy.
This inverter can produce AC 120 (L+N) , Between 120V hot wire and Neutral wire power is 3000W, when you choose the inverter, pls make sure the inverter power is 1.2 times than the inductive load power.The built-in battery charger accepts generator or grid power (AC 120V ) to charge the battery and power AC household appliances. .

Multifunction
- Auto Generator Start: The inverter can start up a generator when battery voltage goes low.
- AC/Battery Priority: selected by SW5.
- BTS : it can monitor the batteries for extended life and longevity.
It is widely used for off grid system , RV or home power emergencies,In an off-grid solar system, your solar panels charge your deep-cycle batteries instead of powering your household loads directly. In addition to converting DC to AC power, the inverter charger can also assist in charging your batteries from an AC source like a generator.lets you take the RV off-grid and still use your refrigerator, lights and other appliances.

I installed this inverter in an off-grid solar system in a waterproof security box on my dock. Mainly for powering a boat lift which draws around 1800w max. That motors continuous load is about 50% of this inverters capacity (according to the lcd display on the inverter). This is a low frequency type inverter so it’s surge capacity (9000w) can be held for MUCH longer (20s) than most normal high frequency inverters (usually measured in milliseconds). This is helpful for starting motors or appliances that are close to the 3000w rating of the inverter. The remote turn on switch is extremely helpful for quickly turning on the inverter without unlocking the electrical box or locker. All inverters draw power when they are on, even without anything attached to them. You don’t want the inverter to be on if you aren’t using it in a fully solar system like have. The remote turn on switch makes it easy. The cable/wire connections are large and feel heavy duty. Communication with the company before and after the sale has been easy and helpful. Product manuals are easy to find on their website and are helpful. I’m happy with the purchase!

After adding 900 Watts of Solar and 400Ah of LIfePo4, I was looking to upgrade from an OEM GoPower1000 Inverter....I subscribe to All About RVs, and Jared Gillis posted a video review that included the Sungoldpower 3000 ...After Comparing specifications and cost to other brands, various customer reviews and of course Jared's belief in the product, I placed the order directly through Sungoldpower's website.Excellent customer service, quick shipping and follow-up communications!I've since installed and utilized both Inverter and charger functions. I've relegated my OEM WFCO charger to backup status. The Inverter has worked flawlessly with my Softstart 13.5 air conditioner, microwave, coffee maker and all house current needs while dry camping!I highly recommend this product and SunGoldPower!

I am impressed with the quality of this inverter.I have a large portable air compressor that most 15 amp home circuits won’t support. This inverter with an 80’ 12 gauge extension cord runs like a champ. It was using 62% power to run it. That says a lot when the power in my truck is better than most home circuits!

My invertor in my class B motor home failed, so I needed a new one. I wanted to replace the old one with a similar size, as space was an issue for me. After much research and review reading, I settled on the SunGold Power 3000w pure sine invertor. After watching several YouTube videos, I tackled the swap-out. It went much easier than I anticipated. And, everything functioned correctly.Fast forward a few months... I flipped on the remote on switch, but nothing happened. I went to the invertor and tried turning it on at the unit. That functioned properly and the unit powered on. I removed the remote switch and saw corrosion on the back. I wrote to SunGold Power and within a day, they contacted me and stated a new remote switch was on its way. Three days after that, the switch arrived in the mail. With an easy replacement done, everuthing works perfectly again. I am super happy with my purchase and the excellent (and quick) customer service. Thanks SunGold staff!
