On earlier LiFePO4 batteries for both Radian and XW I built a precharge resistor circuit that goes across the 175A / 250A breaker. I used a momentary push button switch inline with a 10W 10 ohm resistor. And probably should have also used an inline fuse holder. Press the momentary switch for few se
Thx Nick. The limitations on specific BMS is quite interesting and disappointing I couldn’t start a 1/2 a radian with 60kwh of older style eg4. But with just a bit of solar on it started it no issue. So there is a real problem with the limitations on inrush. JayOn Dec 11, 2024, at 12:07 PM, Nick Lu
Hello again Wrenches,
Some minor developments in this last week and figured I'd share my
experiences so others will be prepared and not stuck in the same situation
as myself. I was able to test this with a brand new out of the box Radian
and another new Powerflo 16 and had the exact same outcome.
Hi NickI remember I tried to start a radian with 60kwh and it wouldn’t work. Yes just 1 power module, but with just a bit of solar connected it started right up. Obviously a nighttime restart isn’t going to work. All the other inverters I’ve used haven’t had an issue so something unique to the desi
Good afternoon Jay,
16 KWH's when full, appears that my first two shipped at 34-50% SOC.
Enjoy your evening, Nick

How many kWh of battery do you have. Jay On Nov 10, 2024, at 11:00 AM, Nick Lucchese via RE-wrenches wrote:Thanks Logan, Tyrone and Maverick,Yes I've tried all the things noted so far without any success. Since there is no PV nor controller at the moment I can't test with just a controller alone
Thanks Logan, Tyrone and Maverick,
Yes I've tried all the things noted so far without any success. Since there
is no PV nor controller at the moment I can't test with just a controller
alone but after testing with the Rosie I'm quite certain the battery is
just fine. Also to be clear, the Mate3s n

Upon further review of your message (you don’t have PV input). Try turning on
just one inverter 175A (half the inverter) prior to battery boot up, then turn
on the other half as soon as it does boot. That will split the start up surge.
Also may identify if an inverter module is working.
Maybe a silly question but have you tried shutting off all load breakers(ac
output) and charge controller breakers before powering up? I've noticed
radians have a hard time powering up on homegrids if they have a load. If I
have to do a hard reset on a radian I also shutdown the charge controllers
Hi Nick
There are PF16's running open loop with Radians. The PF16 has a precharge
built in. The key is to have the inverter breaker closed, then close the
battery breaker. After that push the BMS power button (3-4 seconds the
display will power up) and the battery will slowly ramp up and do a
prec
Greetings Wrenches,
Wondering if any of you have successfully paired the new Powerflo16 with a
GS8048-A yet? There is no reason it shouldn't work yet I've unsuccessfully
been to a customer's site three times now without a fix. The Radian setup
had been in use with an FLA Trojan pack for years till
