Collection: Four-Day Boondock Solar Kit

400W on the roof and 200Ah in the bank is the size that stops a long weekend being a rationing exercise — lights, water pump, a 12V fridge, phones and a laptop, with the array replacing what the night took. The MPPT is sized on charge current, not model number: 400W at 12V is about 28A, so the 100/50 is the controller, and it is both cheaper and larger than the 150/45.

This collection holds every part in the kit so you can swap a size before you buy. The whole kit, priced and loaded in one click, is on the RV power bundles page.
