Growatt INFINITY 1500 Portable Power Station

Hey Pedro (review above) Just wanted to mention that In the Youtube review by HoboTech of this product he points out that within the app you can lower the inverter output and in doing so reduce the fan speed as well FYI. Hope this is useful info for you :>

This little thing works for our setup. We are currently going through our 1st winter off grid with our solar system. Through the summer our house system works great. In the Fall/Winter, it needed help at times. We have a Predator 3500 (actually 3000 watts) as backup. But of course, it's on the brink and isn't starting right now. I really didn't want to buy another gas generator when I noticed Growatt came out with this little bad boy. And since I have the SPF 3000TL LVM-ES from Growatt running the house and am pleased with the build quality and how it performs, I figured I would try out their portable power station. I love the fact that it has 3 charging methods (solar, AC, or DC from a cigarette lighter). Another big plus is that it doesn't require you to use proprietary solar panels. I basically have it hooked up to 3 spare 200 watt solar panels that I have laying around with standard MC4 connectors. If and when I need to charge charge the batteries for my house, I have no problem plugging this in to do so. I have been in connection with Growatt tech support about once a week for over a month. More or less just trying to make sure that I'm not doing anything wrong or that my expectations are in the wrong place. I will say though, when the temps are above 60F and the solar is charging, the fans work very loudly. Took a video and sent it to tech support and he confirmed that things are fine. With that said, it's awesome to be able to talk/email tech support for a product that you spend money on. We keep ours in our full size van, which is our everyday vehicle. We eat and sometimes sleep in our van. Usually we have a 120 watt inverter plugged into the cigarette lighter. This totally replaces that and so much more now, it's no problem to charge 4 laptops. This gives me the confidence to add a small oven in the van also. I've even jumped the van's battery off with a 110v battery charger (which now we keep in the back of the van also). The ultimate plan is to mount 2 panels on the roof to keep it charged. All in all, I love this little power station and it works for our purposes. I'm not trying to run my house off this and know the limitations of it.

I think it was worth the money. Very happy with it!

This will run my entire office (desktop and 2 monitors) for about two work days! Starts and runs my freestanding 12k BTU AC unit and has no problem with refrigerator/chest freezer. Recharges super fast! My only complaint is the fan profile...It's fully charged next to me with no load, but the fans kick on every few min. Would be great if they could back the fans off a bit in future updates. I absolutely would recommend this unit and am very happy with the purchase.

Hello
I’ve bought two units. The 2 unit was bought a weeks later.
The first one charged up at 1440 watts
The second one would only charge at 650 watts max.
Why is that? I used the same outlet in my house for the 2nd nothing else plugged in.
I’m kind of worried it’s going to take longer to charge.
One thing- the first unit was at 35% battery and the second unit was at 45% when I received them.
Thanks
