Solar is Changing !
Yes, many things are normalizing and moving towards "Set Standards" which everyone will comply with... is that wrong ? NOPE, happens to everything over time.... It comes down to safety systems, communications & interoperability... It's the bumpy path forward just like any tech out there. Right now the Solar Technologies are somewhat of a Wild West free for all and the result is equipment that does not interact, varied designs & specs, some equipment which can be downright dangerous.
Right now you can buy prebuilt rack mount batteries with RS485/CanBus etc... BUT they are not all compatible with each other or even teh Inverter systems tht they are connected too.... Would it not be a good thing to be able to buy an SOK, Ampertime, Victron and say a Seplos Battery Pack and be able to plug them all in, interconnect them and have them work and interact using teh same protocols ? CAN'T NOW unless you have a Kludge in between and even then it's a "maybe".
Look at all the AIO's out there that can be paralleled BUT you cannot intermix models let alone brands ! They all have their own proprietary specs and they do not have to be compatible with each other.... Makes things far more complicated than nescessary....
