Andrea,I do not see any problem between those two modes. One note, however. Make sure that you connect the battery voltage to Type94's "load voltage" input (input 3) and that you use Type94's "array power" output (output 3) and NOT the "power at MPPT" output. This models a situation where the battery voltage is the load voltage as seen by the PV. This type of system is quite rare though; even in off-grid applications, the system includes a battery charge controller that includes an MPPT (maximum power point tracker). If your system includes a max power point tracker then you might consider using Type47a and Type47b. If you are using Trnsys17, I can send you an example of such a system that I recently made.

thanks for your help I'm new using TRNSYS, this is my first project with this softwareI am simulating a solar system off grid, I connected the solar panel type 94a to the regulator-inverter type 48d and fed back to the battery type 47b. I'm connecting as load type 14h.I have doubts about - What are the correct modes of type 48 and type 47 I should connect - The type 14 is the load? Or how I can simulate the load? I understand very well the TRNSYS Help, I ask for your help thank you so much
