Hi, everyone - new to solar, reading as much as I can but retaining is a whole other issue. I'm overwhelmed to say the least. Am I at least on the right track for a small system, full time van living in the PNW? Hoping to spend around $1500 (hahahahahahah). Thank you.
My expected watt hours:
Fridge/Freezer (guesstimate based on comparable systems) 500
LED lights (8 lights x 3w x 5 hrs/day) 120
Fan (6w x 24hrs/day) 144
Phone chargers/laptop chargers nominal
Total watts = 764/12v x 4 = 255Ah
Am I doing this right so far?
Eventually I want to add an inverter to my system. Did I do these calculations correctly? I followed the lead of one of the mods:
Magic Bullet (900w / .8eff) 1125
Insta Pot, a girl can dream (700w / .8eff) 875
I'm thinking 300 watts solar and tapping into the alternator via an isolator.
PLANNED PURCHASES
Panels
Grape Solar 180w panels x 2
Charge Controller
Bogart Engineering SC-2030 Charger <--30amps max
*am I correct that I need a CC rated at least 23 amps? Vmpp on these panels is 19.67
*is a PWM sufficient with my system?
*I want one without a web interface
Monitor
Trimetric 2030-RV Battery Monitor
Batteries
Two 6v 225-255Ah Interstate FLM batteries wired in series
Inverter
I don't know which one yet. I do remember a mod here saying never to use more than 1000w in a 12v system.
Battery Isolator
Who knows. Haven't started researching yet.
