Renogy 48V 3500W SOLAR INVERTER CHARGER

[Blakes]

Follow up... I saw the comments on the video about the fact that the solar generation limit appeared to be 8A instead of 80A and maybe it was an off-by-a-factor-of-10 problem and made it my mission to figure this out. I had planned to figure out a way to use the RS-485 bus to configure the settings, but before I got that far, I paged through the settings on the device and found an undocumented setting in the menu: 36. It was set to 5A on my unit. Range is 0-80. I set to 80A and now I am able to pull the full 1200W from my array in full sun! Hope this helps folks!

I completely forgot about that setting.

I haven't touched my unit in a few weeks now. Seems to be working.

My dilemma is that it doesn't appear this thing is UL listed and won't pass code...

i got the same renogy. i am trying to set it up. it seems to default to 12 v system and i have a 48 v battery. i want to set the voltage to 56 but it seems to be set at 60.. how can i change it. i go in to admin and input the new voltage but when i go to the next setting it reverts back to the 12v. help

anyone have updates on this unit? I am considering it - mostly because I may be installing the batteries and inverter/charger in a dedicated bunker/shed to keep the batteries from freezing in a cold climate cabin and to isolate the fan noise from the unit, but would want easy remote monitoring, and I have been impressed with the range of the renogy bluetooth module I used on one of their charge controllers.

Few comments on the new 3500w renogy inverter.

Default is to pull 40amps from the grid, which in my case is a couple of yamaha generators. I have a 2000w ef2000 and 7200watt industrial. Neither can provide 40amps at 120v ac, so I had to change the settings to only pull 15amps from the generator.

Working great.

Are you sure it’s 40 amps at 120v? I am pretty sure that would be battery voltage (48v) at 40 amps.. so like 12.5 amps at 120v. Every inverter is different, but something worth looking into.

FWIW my 35/4800 does not work below freezing lol. It gives a "inverter over-temp" warning. I had to use a battery powered heat gun to heat it above freezing, then it would kick on........

Coming late to this thread, but I have had this unit in my RV for over a year now, and functionally it's great, but the menus are a bit confusing, and you have to set them at the unit ... there is not remote control, which is a pain since it's under the couch and the screen is not easily accessible. I'm using it to run (20) 50-watt panels that I have on the roof. I used smaller panels to cram more panels into limited space and get higher voltages. I have 4 strings of 5 panels each on the roof.

it's 40amps / 48v about ~ 20amps at 120, which makes sense.
