Re: system won't automatically shift into selling mode

Was the Radian at 1.6.63 Firmware before the update? It shipped to me in September 2017 so based on that I believe it was 1.6.63. Make sure the inverter charger settings for Absorb and Float are at least .2 below the charge controller targets. Make sure inverter Absorb charge time is < the charge c...

Re: system won't automatically shift into selling mode

I may end up doing that. I suspect something else may be going on though, as I've had this issue occasionally since I first commissioned the system in 2017. What's odd is that adjusting the sell voltage has absolutely no affect even when the inverter is selling. The only way I can regulate the volta...

Re: system won't automatically shift into selling mode

Just a side note , when the CC is grid enabled it raises the float voltage to the absorb setting to increase the delta from the sell voltage. in this manner you can keep the sell voltage just under the float voltage. If everything works according to plan of course. Yes, this is a nice feature, unfo...

system won't automatically shift into selling mode

I recently upgraded my Radian 8048A's firmware to 1.6.7 and since then it no longer automatically shifts into selling excess power after charge parameters are met. Not sure this is directly related to the new firmware, but in any case I'm having trouble solving this issue. Instead of selling power o...

Re: Which batteries?

Anyway, I thought to ask if people would indicate the make of the batteries in use (in their RE setup) I chose Rolls-Surette, partly because experienced installers around here seem to like them, partly because they're made not too far away from me over the border in Canada, so shipping isn't a big ...

Re: New Radian question

Thanks for the correction. I was given the 350 amp-hour figure over the phone by an Outback Tech when I was researching my options during fall of 2017, but maybe that was a "recommended" figure and not necessarily an absolute minimum. Agreed that charging current on a 7kW array would have to be prop...

Re: New Radian question

A little late to the thread here, but I'll add my two cents since I own a Radian 8048A with an array similar to yours (6.4kW) and decided to go with a minimal battery bank just to get started. I spent $3K on 8 Rolls-Surette 550-S batteries, which is just a high-quality old-school flooded lead acid b...

Re: I shut it down for fear of damaging batteries

Great, sounds like you're on your way.

I have the exact same batteries that you have--but just one string of 8 (for now, anyway--will upgrade the bank in coming years). They seem like very solid "old-school" batteries, rugged and well-made. Time will tell.

Re: I shut it down for fear of damaging batteries

Sorry to hear about all the trouble, that's frustrating. First question: have you looked at the Rolls battery manual so you understand their charging parameters? If not, I would start there ( https://rollsbattery.com/public/docs/user_manual/Rolls_Battery_Manual.pdf ). Same for the MATE3S guide ( htt...

Thanks for the info...I was just assuming they made DC AFCI breakers. What's your take on AFCI? Are you seeing a lot of "nuisance" trips?

I did not install arc-fault breakers in my two combiner boxes when I installed the system two years ago.

My Radian system is housed in a shed about 25 feet from the house, but the main service panel and my sub-panel for backup loads are in the house.

My system's been online for almost 2 years now and I feel like I have the settings dialed in pretty well. Normally I'm grid-tied with the battery bank full, so the morning routine is just a brief bulk phase to get the voltage back up, then an hour of absorption, then the rest of the day I'm selling ...
