        I see that it's compatible with a solar panel. Can I recharge a 40V battery while it is docked on this? If so, how long would it take to recharge a 4ah or 6ah battery?
        ByMar 3, 2026
        2 Answers | 
        Answer This Question

        ONLY the USB ports are active when the battery is being charged via solar. You find that out in the fine print of the manual. No 120v power while being charged.

        By|Apr 6, 2026

          (1)

          Hello, Ryobinoob - Yes, you can use a solar panel to charge a 40V battery while the battery is docked on the inverter. With our RYOBI 60W, solar panel, it can charge a 4Ah battery in 3 hours and 12 minutes. If you need further support, then feel free to ask another question.

              How does this new inverter compare to the older model (RYI300BG)?
              ByFeb 28, 2026
              2 Answers | 
              Answer This Question

              Two standouts for me. The USB C is now PD, which means potentially higher output but also 2-way charging. The AC outlet is also now pure sine wave, which is more compatible and safer for some electronics and appliances.

                (1)

                Hello, Ryobigirl - This new inverter has two USB-C outlets, and the RYI300BG has only one. The RY40BG02B is solar-charging compatible with the RYOBI 60W solar panel and has individual on/off switches for the task light, USB ports, and AC outlet for isolated power to conserve runtime. It also has an auto-shutdown feature that turns the unit off after three hours of inactivity. If you need further support, then feel free to ask another question.

                        Just what I been waiting for!
                        [This review was collected as part of a promotion.] I really like this I was waiting for the old version to go on clearance then saw these were coming out and then jumped on it right away I've been using it with a pair of 40V 6Ah battery to clear the driveway from snow. The price was great and the fact that it can charge the battery too is outstanding, mine is a tool only but it came with a 240W USB C cord that I have plugged into a 60W Ryobi charger brick from the 1800W 18V power station. It's charging it fast and has no problem keeping my little snow blower running. Can you recommend a bigger charger? Something that'll put this to its maximum potential? I'll really put this to use when I start camping I plan to hook it to my 100W solar flexible panel see how long it takes

                            [This review was collected as part of a promotion.] This review was collected as part of a friends and family campaign. Love this 2-in-1 unit! I’ve powered my laptop, phone chargers, lamps, and TV during outages with zero hassle or buzzing. Being able to charge my batteries (from the wall or solar) is an incredible added feature! If you're in the Ryobi 40V ecosystem, this is a must-have—quiet, reliable, and beats a noisy gas generator for small needs. Highly recommend!

                                [This review was collected as part of a promotion.] This review was collected as part of a friends and family campaign. I recieved this to test since I own several different brands of inverter. This inverter performed well running a TV and game console for over 4hrs on a 4Ah 40v battery. The fans only came on a few times and were resonably quiet. The controls and compactness are where it shines. Simpler to operate than others I have and of coarse my existing batterys fit. My favorite by far of my inverters. 300 pure sinewave is great for my uses. Love the built in light too.

                                    Pretty nice system...Versatile for most small amperage pulling, small appliance needs.
                                    I bought this as one of those "in case" purchases. I haven't used it because many of my 40 volt batteries have elected to die as Ryobi likes to do. I'm sure that when I get the time I can watch an internet takedown and fix them while not paying $2-300 for new ones since some of these have minimal time on them. But yeah, this is a device that will give me confidence when power loss or even camping.
