Renogy Smart 100 ah Batts variety use communication interconnects and you can see them connected in two banks going to their Bluetooth Dongles on the wall in original post. Apparently they undertake auto balance functions on charging so they do see and talk to each other in the string.

I have the 4 Renogy Smart batts and wired using the halfway method. Really wanted 5 but whilst I understand balancing parrallel banks, I think the OP may be referring to the BMS interconnects as their Renogy battery monitor can manage more than 4 interconnects but the Renogy manual say max 4 or...

Yes all 4 fixed are in parallel as the Renogy 50a is limited to a 12v system only. I then started to realise, if I change to 3 on one and 2 on the other, then it’s all the little rewiring, fusing etc. that comes into pla. So will set up the second scc for temporary only panel with the portable...

Hi all. I have 5 x 180w (12v) glass panels all of the same type. 4 are mounted on roof of caravan and fed into the Renogy DC50amp controller. The fifth panel is not mounted so use as portable. Also have a Renogy rover 30amp controller given to me. Would I leave the 4 in place with the 50amp...

I just went through this and the Meanwell TS-3000 (12v-230v) has a high standby current for small devices so in went a Victron 12/250 to run all these light application. Both of these units do have ECO modes as well but I am having trouble understanding their effective use as things like...

Each battery is supplied with the button to lan connection, I had 4 so tried another with success. There is another post to show it is just a 2 pin short.

I originally thought with 2 plus batteries, the shelf mode option was gone on the basis, the other batt/s would wake up the one your putting to sleep Notwithstanding they are network connected. Then I tried a different button and presto, got all four to shut down (no Solar and AC charger off of...

Very happy with this unit and have the 50a version for past 6 months. After reading all the alternator side of things, went out to the caravan to test. Have a smart alternator. Isolated the solar input and with no sense wire attached, the unit delivers a 25amp charge (24.93v), then again with...

Hi Folks, As per the title I installed the Renogy 4 100ah smart Batts all linked with 95mm cable using the 'halfway' method of interconnects as per the Victron wiring publication. Further DIY the network cabling. Renogy sells a network communication hub so the BT-2 connects to the primary port...

Thanks, that makes sense now on insulation rating. unfortunately in aus, there is little regulatory in Caravans on the 12v side.

Thankyou for this. The Meanwell is the 12v variety 240v and was gifted to me hence why it’s going in. The maths on fuse calculation is great as gives the understanding. The only part I found a tad difficult was the various cable current ratings from high quality suppliers. For example one major...

Update, I checked the specs of the cable and is has a current capability of 416amps in air and 221 in conduit. So from reading, this fuse is there to protect the wire itself, therefore I think I could safely put a 350a (lower than total output of the batts) but more than enough for the...

Okay, so I have 4 x 12v 100ah Renogy smart arrived today and will be in parrallel. My inverter is 3000w Meanwell. Using 3/0 cable and total path of cable lengths is under 2 meters total path. My inverter will never really exceed 2200w with single devices only in caravan. I was originally told no...

Thanks for this and another question. If I parallel 4 then they auto-balance but if I have 5 in parallel, I take it the fifth just does it own thing in charging up. Surprisingly Renogy say up to 4 recommended, yet in Australia they are advertising as "unlimited parallel' connections (ebay au)...

Hi Folks, first post and have been reading wide so as to upgrade my caravan as ready to change from AGM to Lithium Batts. Currently 720w Solar through MPPT lithium ready ( currently 12v AGM's), 60a AC to DC Lithium ready chager. I do have a quality Mean well 3000w inverter 12 to 240v that I...
