I am planning an off-grid Zero Energy residential Building made from a shipping container. The building will have a PV array and battery storage. The goal is that pumps, fans, heat pump, lights, fridge, slow cooker, computer and water heater all be DC powered (12 V system, except heat pump which will be 48 V). I plan to use a MPPT charge controller. I want to be able to control and monitor the energy system with a Building Energy Management System (BEMS). I think existing BEMS solutions may not be suitable for this research project, since it is a DC system with components from different manufacturers. Would LabVIEW be suitable to display and log the PV production, battery charge status (communicate with a Battery Management System), turn on and of equipment like lights and set up schedules and conditional rules for powering on/off equipment? Do you have recommendations for hardware, like energy meters, that I can connect with LabVIEW? I suppose I also need a hub that is connected to the computer. Is wireless solutions much more expensive than a wired system?
