OutBack Power Radian 8 kW Pure Sine Inverter GS8048A

Inverter arrived right when expected and is working well. Replaced a pair of 36048s being used in master/slave configuration.

Grabbed that along with panels at their fulfillment center at Orlando. Very nice people, know their job. told me all about driving all this solar stuff home safely.

Quite a convenient model, easy to program. The efficiency could be better, but for this money it’s a very good deal.

OutBack Battery-Based Pre-wired Inverter 8.0 kW FLEXpower...

ok, i basically purchased this instead of getting an inverter and controller for my panels. quite convenient indeed and very easy to setup – i just basically hung it on the wall in the garage, connected it to my PV system and main panel and ran its standard program and voila. approved.

I was very pleased with the speed of delivery, thx! Yesterday we’ve finally finished the installation, everything is in place. The inverter works, it is very silent, let’s hope it stays that way.

OUTBACK Charge Controller MPPT 60A Battery FM60-150VDC

Awesome charge controller! Yes, not the cheapest, but if you want to get an MPPT charge controller, I suggest you give this brand and A1 a try. I like that it can store 128 days of data, allowing you to see trends over time.

OutBack FLEXmax FM100-300VDC 100A 300Vdc MPPT Charge Controller

Works great with my li-ion batteries. Don’t expect any miracles from this unit, but it is a durable workhorse that can be installed outside without worries. I also liked the service and a pickup option, it saved me a lot of time.

OUTBACK Charge Controller MPPT 60A Battery FM60-150VDC

Excellent quality! Very well made. Had a bit of a problem with setting it up though.The manual is 126 pages long! Could not get customer service after waiting for 13 minutes. Would buy it again, but this time hire another electrician other than myself to help with the installation.

OutBack FLEXmax FM100-300VDC 100A 300Vdc MPPT Charge Controller

I did my research before the purchase and you should do the same. Under my circumstances it was the best option, but keep in mind that it requires MATE3, MATE and MATE2 are not supported.

OUTBACK Charge Controller MPPT 60A Battery FM60-150VDC

I took an FM60 to Haiti recently. Very hot and high humidity. We coupled it with eight 180watt 26v modules. The controller was very easy to set up, and the charging began immediately. We had a 24v battery bank (8 x 6v). We put some heavy loads on it like pressure pumps, a big miter saw and a fridge. The unit never missed a beat.

Thanks for the service! The package came in like 4 days or something, very happy. I followed your guidelines and installed the inverter in the garage. Hope that this one will last longer than my last one. Stay safe!

I owned a cheap 30A controller before. It clearly wasn’t up to the challenge of marine life. Installing this one was very easy, and now I enjoy fully charged batteries even on cloudy days.

The inverter is obviously too small for a home installation, but it fits my RV system just fine. The installation was a bit messy, cause my van is so old. your articles on the setup actually helped quite a bit

OutBack Battery-Based Inverter 2.8 kW VFXR2812A

Overall, it’s a good model for a camper van or a boat for its money. The efficiency isn’t the best, but it works well when it’s hot, the warranty is all right and it’s somewhat programmable. I picked two of these and they've been serving me for 6 months now.

OutBack Inverter 50A GS4048A-01

Bought this model four month ago. Before the purchase I discussed with my electric supplier the possibility of grid connection and net metering. The procedure was very simple and my installer also helped a lot with little details. Now I sell into the grid basically half of what I generate. Very happy with myself and my purchase, so thank you

OutBack Battery-Based Inverter 2.0 kW FXR2012A

I installed this one on my yacht a long time ago, but it started clipping, because I added some stuff on the board. Anyway, I decided to buy another one to stack them. The retailer from which I purchased the first inverter went out of business, but luckily i found the same inverter here. The prices are good and the shipping was fast. Thanks a bunch..

OutBack Power Radian 8 kW Pure Sine Inverter GS8048A

I picked this one for our Texas ranch where we live solely on solar energy. grabbed it at the warehouse in Arlington. It is a well-made product, quite heavy, but high-quality nevertheless. I backed it up with batteries and they made living off-grid a much more comfortable experience.

Purchased this one for my boat a year ago. Came back to find optimizers and decided to drop you a line and say thanks. Generally sea air doesn’t sit well with inverters, but so far this model is doing well.

We are not connected to the grid and all our energy comes from the sun. That’s why we need a backup for everything just in case. OutBack makes reliable equipment, hence our choice.

OutBack Battery-Based Inverter 3.6 kW VFXR3648A-01

Thanks! It’s been a year since me and my family went off-grid: the power lines here aren’t really good and we often sat in the dark for hours. Since we’ve installed solar, these problems have gone away. We also grabbed some batteries from you to have a supply for the night, they are nice.

OutBack Power Radian 8 kW Pure Sine Inverter GS8048A

We used this inverter for our gas station in Ohio. The system is quite big so we had to get two of them. The results do not disappoint: we basically nullified our daily needs in commercial electricity. and at night the energy is cheaper anyway. Thanks a lot for the fast delivery!

OutBack FLEXmax FM100-300VDC 100A 300Vdc MPPT Charge Controller

Great charge controller, but I wonder why they couldn’t add a small display that you can see in so many other models. If this is an important feature for you, you will have to look through other options, but overall it is an excellent device

We bought two of these a year ago for our home system. My husband actually used your calculator to size the installation. The inverters still work fine even though it can be quite dusty here in Arizona. just wanted to thank you once again for your amazing service!

OutBack Battery-Based Inverter 3.0kW FXR3048A-01

I purchased this inverter and so far I’m impressed with how well it withstands the weather here in Arizona. Each of my two previous inverters died within six month after the purchase because of the dust and heat, but this one is already 1 year old and is still going strong.

OutBack Battery-Based Inverter 2.0 kW FXR2012A

Thx, I picked this model for my RV four month ago and it doesn’t disappoint so far. I drive around a lot, but since I installed solar, I don't really need camper parks anymore. There isn’t a lot in my van — a laptop, lights plus some stuff for cooking. this is why I chose an inverter with a little capacity — it’s enough for me.

OutBack Inverter 50A GS4048A-01

A strong reliable inverter. In our cause it handles even a little more than expected, since our system is 4.2 kW in size or around that. I watch my system like a hawk and check everything: gotta hand it to him, it has very good efficiency. Overall, a solid product, would definitely recommend it.

What if my system is bigger than the capacity of this inverter? will this one still work?

A1 SolarStore

If your system generates much more energy than the inverter is rated for, clipping may start. Basically, you will just encounter power losses. Obviously, it’s not good for an inverter either.

Do I have to get batteries for it?

A1 SolarStore

No, having a battery bank isn’t necessary.

lastscann

05/10/2021

where should i put it? will the exterior wall of the house do?

A1 SolarStore

Good day. While sometimes exterior walls can be an option, this inverter isn’t rated for outdoor use. The best option would be a dark, dry, cold place, like a garage.

About product

OutBack Power Radian Grid-Tie Hybrid Inverter, 4.0kW 48VDC, 120/240 VAC, 60HZ

OutBack Power Radian inverter can be used as a grid-tie or an off-grid inverter. There are two separate AC inputs: for the bi-directional grid connection and for an optional backup generator. The inverter is well suited for both commercial and residential applications as it can support large dynamic load variations and surge loads.

Each Radian inverter requires dual 2/0 AWG battery cables (two positive and two negative) for connection to the battery bank. They have an adjustable input-voltage range so they are compatible with most battery technologies. Up to nine units can be combined for three-phase operation and ten in parallel, single-phase operation. A MATE3s, HUB10.3, and an appropriate GSLC are needed to complete a Radian system. Not rated for outdoor use.

Features:

4,000 Watt backup power
Built-in 50 A transfer switch at 120/240 VAC
96% peak operating efficiency
175 Ah minimum recommended battery size
7 different programmable operating modes, with generator assist
Remote temperature sensor included
5-year warranty
Dimensions: 28" x 16" x 8.7"
Weight: 82 lbs.
