Description

The inverter charger combines the inverter and battery charger into one complete solution. It transforms the DC power stored in the battery bank into standard household AC power. It also recharges popular 12V house batteries when AC power is available. The integrated transfer relay with neutral ground bonding allows switching from shore power mode to inverter and vise versa ensures your RV doesn't lose power unexpectedly. Built-in Bluetooth connectivity allows you to monitor and manage it. The REGO 3000W Inverter Charger transforms the DC power stored in the battery bank into standard household AC power. It also charges and maintains the battery bank when connected to shore power. The inverter charger is compatible with all kinds of popular 12V battery types, GEL, AGM, SLA, FLD, CAL, and Lithium. Ideal for applications going back and forth from shore and inverter power automatically. The built-in Bluetooth allows you to monitor the status of the REGO inverter charger via the Renogy App directly on your smartphone. The device can also connect with the Renogy One M1, the all-in-one dashboard provides you access to accurate real-time energy data of your whole system. *Note: Renogy One M1 is sold separately. The REGO 3000W pure sine wave inverter charger utilizes 4-stage charging(Bulk, Boost, Float, EQU), to maintain the highest state of charge for the battery. This ensures the battery can be efficiently and automatically charged to 100% and maximize the battery lifespan. The REGO inverter charger features a bright LCD display that allows you to easiliy identify the current operation status and alert messages. You can easily navigate the display pages or set the parameters of the inverter charger with the four function keys below the display. The input voltage range and battery charging current are configurable. Easy access panels make connecting the REGO Inverter Charger a simple affair significantly saving time during installation International certifications: FCC Class B Part 15 Compliant, UL458 (including Marine supplement), and CSA-C22.2 No 107.1. Q: Can you use 2-100ah lithium ion batteries with the 3,000 watt inverter? I think I read somewhere that it requires 3-100ah batteries. A: Yes you can but many lithium batteries will have a BMS (battery Management system) that can limit the output current. Most (not All) 100 ah battery manufacturers will limit current to 100 DC amps continuous. If this is exceeded then the BMS may turn off the battery. So (2) 100AH batteries may have a max current of 200 amps. This would not be enough to drive all 3000 watts for this inverter but you should be able to do about 2000 watts. You can but the batteries may not be able to put out enough current to get 3000 watts out of the inverter. Q: How do I attach the temperature sensor to the batteries? A: I wedged mine between a couple of the leads that connect to the battery. Q: Anyone having trouble running a 1100 watt microwave with the 3000 watt unit with nothing else on? A: Ours does fine - but check to make sure your wires are heavy enough gauge to handle it. Q: I asked this before and got an answer that didnt answer my question what generators are compatible with this inverter? Links to any? A: Any 60/hz generator is compatable with inverter/charge. The inverter having electronic component would be ideal with inverter type generator. I use 6k onan generator with no problem. I have notice to charge batteries it draw quite a bit of power. For 1k inverter I would recomend at lease 3000 watt generator. Q: What are the implications of getting a 2000 watt vs 3000 watt? I will have a total of 630 watt in solar panels and 100-200ah lithium battery. A: I sent mine back because it limits the system to 24 amps regardless of it being a 30 or 50 amps system. A whole lot of stuff is the trailer won't be able to work.

Great Inverter/Charget for the price
The first one I received wouldn't invert D/C to A/C. These things happen.... Renogy was very helpful and we troubleshooted over the phone and they said to send it back. I ordered another one and it's working perfectly. It fits nicely under my Sprinter rear bench seat. I also added the D/C to D/C charger and the Renogy ONE remote screen. Everything works nicely together. ... show more

Affordable and Solid With a Few Caveats
This is my second Renogy inverter. Do your research and make sure to purchase more capacity than you need. 3000 does not really mean 3000 watts. This 3000 easily runs the air conditioner and microwave in my rv and seems to allow full 30amp 120volt pass through on shore power, which my 2000 does not. Charges great. Not the most efficient unit out there on stand by. Fan is a little loud, but not a deal breaker. LCD screen interface is clunky at best, but unit has plenty of adjustability and customizable settings for just anbout any usage situation. Heads up though- included manual sucks! Settings aren’t even fully explained. I gave up on the remote shutoff. It dies not adequately monitor battery status. Make sure you get a shunt and monitor. Lots of good stuff on set up on the internet though. Blue tooth interface is pretty disappointing and Renogy seems to have abandoned the REGO ecosystem, but you don’t need to use any REGO equipment to use this inverter. Don’t forget about inverter cables, bus bars, shunt, and battery cables when budgeting. Adds up fast. About 15 percent of my system cost is fuses, bus bars, monitors, switches and wire. Tough to beat at $600-$700. ... show more

Didn’t work out of the box
This unit would pass power through from the grid but would not invert. Customer service is horrible. Sent everything with the Renogy name on it back and got a blue inverter that is working much better. Warranty isn’t worth anything if the company will not respond and troubleshooting and manuals are far from adequate. ... show more

Missing Cables
It works great for converting solar to usable electrical power. But it is missing cables that need to be ordered separately that makes the Bluetooth feature and temperature gauge work. It's also missing the adapter for solar panel cables and the various cables to connect to a deep cell battery or their own batteries. I bought this on sale for $700, but it's priced at over $1000. For that price, the cables needed should have been included. I ended up going to my local hardware store to buy them individually cheaper than Renogy was offering. ... show more

Weight & size
When I purchased this inverter, I really didn’t have a good handle on how heavy it is and the dimensions of the unit. I would bet the unit works great, but have no idea because I returned it due to its size and weight. I give it a good rating simply because my experience with the manufacture has been pretty solid ( though service is…meh) ... show more

Garbage
Do not buy this junk. Terrible engineering. They give you 1" from where wires are entering to land on the lugs. The termination lugs are not screws, just a cheesy clamp attached to the board which I could easily see breaking
