Hi all this is my first time posting. I've been trying to get a response for weeks on what to buy since they have some good sale prices. But HQST has yet to respond with anything except for an automated email. I have a
HQST 40A 12/24V MPPT Solar Charge Controller paired with 4 HQST 100W 12V 9BB Monocrystalline Solar Panels. I'm trying to add another 4 panels. I know I need another charge controller but I am unsure of compatibility. I cant find any info on my original charge controller. And since my setup is several hours away I only have this picture of it for reference. From what I am reading only certain controllers are compatible with the RS485 Parallel Charge Connection Cable for MPPT Controllers. I believe that as long as I match the 40A12/24v MPPT style I should be ok to add it to my setup but I don't know if this will work with the RS485 Parallel Charge Connection Cable for MPPT Controllers. Id really like to get confirmation if possible if I need to upgrade my exiting controller or just add another with the new panels. And if there are considerations for the controller I may not be away of for compatibility. Thank you in advance for your help!
