The Renogy 3000W Pure Sine Wave Inverter Charger can be used for multiple applications when going off-grid. A power inverter is an electrical device that transforms the DC power stored in a battery bank into standard household AC power for a user's electronic needs. This device can also charge and maintain a battery bank when connected to shore power and now compatible with Lithium batteries. With a low transfer time, power remains uninterrupted when switching from solar to shore power. This creates clean and silent energy without having to worry about losing access to connected devices and appliances. The Renogy 3000W Pure Sine Wave Inverter Charger is a perfect back-up power source!

    Excellent product

    Posted by Taylor on Nov 3rd 2022

    Installation instructions were clear, with appropriate tips and warnings highlighted throughout. Felt like a pretty daunting project at first, but that made it easy. Be sure to research ahead of time, but if you want an off grid system, this worked great for us.

    Another Home Run

    These folks are putting together exceptional solar power and off grid products. They are well engineered in exacting detail. Their prices are very competitive. They deliver on time as promised. What a wonderful company. I am grateful that they are in business.

    Great unit just wished it worked a bit differently

    Posted by Vkilin on Aug 17th 2022

    This all-in-one unit is simple to wire and simple to use. My only gripe is that it needs to be turned on to even operate in bypass mode when you have shore power. The automatic transfer switch is very fast and with four 100Ah LiFePo4 batteries and a MicroAir Easy Start, I can run my A/C for four hours using this unit. Even though I am using 4/0 wire and very short runs, there is a slight high pitched whine but its common for many inverters. However I only hear it in inverter mode under certain circumstances and there is no other noise in the trailer. It is a large unit and very heavy. I did wire a 300A T-Fuse and cutoff switch between the batteries and this unit so I can positively turn it off from inverter mode.

    Works as intended

    Posted by Twalka on Aug 17th 2022

    Everything works as expected... I did wire in my own transfer switch because of the reviews I had read but... I definitely recommend this inverter/charger.

    Great Unit

    Posted by Greg on Jul 27th 2022

    Nice unit. Works as advertised. Wish it had a remote display, not just an on/off remote. Unit is a bit heavy, but understandable. Would recommend to anyone wanting a heavyduty inverter.

    Simple, elegant, overall a great buy!

    Posted by Vkilin on Jul 27th 2022

    Easy to install and the wired switch has a nice long cable so you can route it to a convenient location. Quite large but works well and running sensitive electronics has been flawless. Easy to read LCD screen and simple menu controls supported by a manual. Great product
