I finally got my other two strings hooked up.
I have 32 cells from Basen (Emily) from around Feb and 32 from Qishou (Amy) from around May. The posts are not in the same place. The posts on the newer cells are farther apart. Both have "eye" shape posts and qr codes match eve. It doesn't matter...
I was wondering what the consensus is for either of these for off grid.
Pros for contactor
cheaper
no hands on to close contactor
Cons for contactor
Uses power
need precharge
Pros for Shunt trip
no precharge required
doesn't use power for breaker to remain closed
Cons for Shunt trip
Need...
Looks like a new toolkit with mobile apps and web interface. I haven't found any dependency info yet so not sure it's usable for older WM4s, etc.

Anybody try it yet?
Has anybody had any luck using these interfaces?
I'm trying to get a Batrium to talk to the gateway with no luck. I'm wondering if the interfaces even work at all. Device detection on rs485 in the gateway doesn't detect the batrium. With canbus, the batrium appears to be sending and getting...
They advertise Xanbus communication as an option. Anyone using these? I'm wondering what type of integration is available? Does the bms signal the inverter to stop charging on high cell voltage or the AGS to fire up the generator on low cell voltage?
I sent them some email but I can't find much...
I'm installing 2 tpm10 top of pole mount (I hope if Solaris actually ordered them). Anybody install these? Any gotchas?
I ordered these from Solaris two months ago and can't get an order update from them. They don't answer email or voicemail. I've been trying for weeks. Anybody deal with these...
I'm looking at setting up EV charging from surplus solar. I can use aux from midnite classics or relays off the Batrium. Both can be set up to start/stop around float state, float voltages or SoC states. So I was looking at a level 2 charger and was thinking of using this or similar SSR...
I have two 16s 280ah strings and want to add 2 more. What is proper procedure for this? My thought was to top balance the new strings and let them settle. Then charge existing strings to as close to the voltage of the new strings as possible and connect them. Each string would be fused and using...
On 2/24 I was told the batteries were shipped and given the Fed Ex tracking number.
I just 3/25 I was notified automatically by the fed ex tracking system that
"FedEx MPS Shipment xxxxxxxxxxx Tendered to FedEx
This shipment was tendered to FedEx Ground on 03/25/2021.

I've got a 280ah cell with some weird behavior.
- When charging, it's voltage leads the other cells. I have absorb set to ~56.1 and balancing set at 3.51v. It reaches this before the other cells which do range with lowest at ~3.46v at that point.
- When it hits the absorb/balancing voltage...
Does anybody know if the latest insight/XW pro firmware allows for the "State of Charge level to Stop Generator" option to be configured for less than 50% SOC? Insight v1.17 firmware indicates "Fixes AGS SOC trigger issue". I'm wondering if they may have fixed the 50% limit too. thx!
I set up a Qucc bms. 16s bank 280ah. I got it all set up and was experimenting with the high voltage cutoff. I found that if a cell is marginally on the cut out voltage the bms short cycles the contactor. Perhaps balancing adds to the issue. Is there some setting that can prevent this? Longer...
Hi,
I'm trying to figure out why my charge rate seems to be capped at ~7000w. It's a Kohler 12 res. The AC 2 breaker is at 50a. AC 1 at 60 (but I'm off grid). Setting Maximum Charge Rate from 75% to 85% makes no difference. I see ~28a on both A2 L1 and AC2 L2. ~90a at the BMS. I haven't...
Hi
I was wondering if there was any consensus on max charging amps for a parallel first string such as a 4p16s of 280ah 3.2? Max current on an individual cell is 1c which would imply 4c for 4 parallel cells. Realistically that's into arc welding territory, but I'm thinking about additional...
