Hi, I’ve just joined this forum
I’m planning an off grid system to run a fridge and freezer in my shed. The shed has grid power but off grid will save me about $500 per year. Max power 600W (when both compressors are on at the same time). Energy budget 3 - 4 kWh per day. I imagine that 2.5 kWh storage should be sufficient to run fridge and freezer overnight. 1000W panels should be enough for sunny days but I may consider 2000W for cloudy days. I will most likely need an ATS so that fridge and freezer still have power when batteries low. I currently have plenty of panels and an old 2000W inverter (not sine wave)
I have not decided whether to go with an all in one system or seperate components. Options I am considering:
1. Victron 150/35 mppt, victron battery protect, ATS, existing 2000 W inverter.
2. Victron 1600/24 Easysolar
3. mpp solar 3000/24
Any advice here, or other options, would be welcome
Energy storage: 2 x 100ah LiFePO4 connected in series. I have not selected batteries yet, still looking for something economical. If anyone knows of inexpensive lithium batteries in Australia please let me know
