Good idea but a fairly critical design failure is the location of the isolator, why would you want to reach over the batteries that are faulting and in the worst case scenario going to catch fire to turn off the isolator 🔥

[@intelligentcontrols]

Good observation but this is ultimately a non-issue. The batteries are thoroughly tested and have UL1973 and 9540A certification. Beyond that these are LiFePo4 batteries that have a greatly reduced base risk of a thermal event just due to their chemistry makeup. When the batteries enter a fault state they individually isolate themselves with internal MOSFETs. The main purpose of the isolation switch is not to protect the user from the batteries but rather to disconnect the cabinet of batteries from the larger system so that in a multi-cabinet system you can do maintenance without having to turn everything else off.

@@intelligentcontrolsthanks for the reply, regardless of certification achieved the fire risk is not zero, not to mention there are other reasons you might want quick and unobstructed access to the isolator, it’s a design failure for me but if I had to use the cabinet I’d just install a more safely accessible isolator if it were my installation.

No one helped me please replay me I have an inverter and it synchronizes only with the Pylon tech battery of lithium the inverter BMS does not communicate with and I set it manually from the lead acid setting
So my question is if I set the battery stop full change value and discharge stop value manually without BMS communication my battery work if it is connected to an inverter to protect my battery

Hi Jason, happy to help. The first thing to be aware of is that your inverter needs to have a lithium charge setting. Using a lead acid charge curve can and will damage the batteries. Look for that setting in your manual. If it doesn’t have it, your inverter may not be compatible with lithium batteries. Once the lithium charge setting is enabled, you can manually enter your setting points to operate the batteries without communication. Here are the settings: Absorption voltage, 52 Volts. Float voltage, 51 Volts. Low Voltage Shutdown, 44 Volts. Absorption time, 1 hr.
