I tried out that solar calculator.
It came back with 530 watts with 55 amp MPPT, 425ah lead acid batteries.
Used winter numbers with furnace at 20hrs per day, 0.5hrs microwave usage, etc
We have 4x 6v golf cart batteries (Duracell) and 2kw inverter. Batteries are a few years old, always connected to 4 stage charger/AC. Believe they are 215ah/each with 2 pairs in parallel (standard for 12v setup)
Likely will be adding a 24/7 camera and internet wifi backhaul link across the top and then down the mountainside to our house. So that will add a little more usage.
so if thats what you are getting , I would personaly pad my chances and at least double the solar panels and batteries. if I got that for numbers I would put 3 or 4 400 watt panels and I would double your battery capacity to help keep the usage under 50% of the battery capacity to get maximum life. and theres no harm in haveing extra battery capacity for thoes stormy few days when you won't get full preformace from the solar.
