Hi Everyone,
While I'm still in the process of testing and collecting batteries I'm already making future plans to (ultimately) power our house completely off grid. I'm planning to go with a 48V set-up, and starting with one 5kW MPP Solar inverter, when required expand by adding extra in parallel. While looking at the available models from MPP Solar I've come across the following models: PIP5048MS and PIP5048MG. The second is the newer model, and as far as I can see the only (for me) significant change is in the built in MPPT solar controller. See the below specification sheet:
I'm also planning out our solar set up. I'm planning on starting with 4 300W Canadian Solar panels (datasheet, see 300MS), later we will add more panels as our set-up grows. Now here's where it becomes tricky (for me), and I'd like to ask for your advice:
1. The panels have a optimal operating voltage (Vmp) of 32.5V and a Voc of 39.7V. If I ware to connect the 4 panels in series I'd end up with a Vmp 130V and a Voc 158.8V, correct?
2. The MPP PIP 5048MS has a MPPT range of 60 - 115V and the 5048MG has a MPPT range of 120 - 430V.
With the mentioned four panels in series I'd be just above the MPPT range of the MS (using the Vmp and not Voc), and when connecting 2 panels in series I'd be just narrowly in the MPPT range.
With the PIP 5048MG with the four panels in series I'd be just narrowly in the the MPPT range, thus I with a bit cloudy weather I'd be just below the MPPT range thus won't yield any solar energy, correct?
Considering my starting point, and possible expansion at a later date, what would you suggest me to do? Go for the MS or MG? And what wiring strategy would you recommend me for my (starting) set-up?
Best regards,
