Re: [RE-wrenches] Battery disconnect solution
I understand that MidNite is working on a new product to replace the BDM. Makes sense actually. I don't know any more than that though. Robin Gudgel would know more. boB 🌜 boB Gudgel 🌜 On 5/9/2022 5:43 PM, Jeremy Rodriguez via RE-wrenches wrote: Does anyone have a solution for operating a remote trip MN battery breaker since the BDM is gone?

Re: [RE-wrenches] Battery disconnect solution
I want to comment, maybe without value. The breaker you mention is called a "shunt trip" breaker. This is common type breaker in the electrical industry. The MN breaker has a 24 volt solenoid that trips the breaker. Shunt Trip breakers have the solenoid voltage for the system voltage. BUT the way it works!! (load side of breaker is connected to one side of the trip solenoid the other side is connected to switch and then to (neutral). When the switch is closed current rushes through the solenoid, triping the breaker stoping the solenoid current. But what to do with solar equipment? Often when the bsttery is dis onnected the losd side of the breaker does not go to neutral and the solenoid can carry current and will fsil On Mon, May 9, 2022, 7:43 PM Jeremy Rodriguez via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > Does anyone have a solution for operating a remote trip MN battery breaker > since the BDM is gone? > > We do have a birdhouse, so maybe someone has a BDM, but otherwise, > what to do? > > Batteries in a dwelling > > > Jeremy Rodriguez > Solar Installation / Design Expert > All Solar, Inc. > 1453 M St > Penrose Colorado 81240 > > Sent by Jeremy's iPhone.

Re: [RE-wrenches] Sol-Ark 15k
I think the idea here is that 690.9 allows the inverter output conductors to be sized based on the maximum ampacity and an OCPD is actually not required is the conductor ampacity is sufficient. So in an off-grid scenario, the wires could be as small as #4. In a grid interconnected situation where there is potential pass-through current exceeding the inverter output current, the wire would need to be protected according to the available current on the grid input terminals. If there is a generator, the inverter output circuit would need to be protected based on the generator rating. The fixed 200A rating of the inverter load disconnect is the confusing part. It seems like it would be more functional if it were replaceable with various ratings of main breaker. You need additional circuit protection in most cases unless it's completely off-grid with no generator input it seems.

Re: [RE-wrenches] Sol-Ark 15k
Wrenches The new solark 15 has a 200 amp rated contactor this is so if you want to have whole home pass through you can but if you only have an inverter then use that as your starting point and if the genny is contributing then add that is, you do not need 2/0 for a single 15 k off grid but you may grid tied. this opens up other issues that are not part of this conversation like multiple 15 and 3/0 grid tied remember KIS!
