Design a Grid-Tie with Battery Backup PV System in Saratoga Springs NY

Design a grid-tie with battery backup PV system in Saratoga Springs NY

The house uses 13000 kWh per year And has 200 A circuit box in the basement Distance from PV to shed with charge controllers, battery bank and inverters = 180’ Distance from inverters to main panel = 150’

1. How many kW of PV do they need to generate 13000 kWh 2. Assume pole-top mount 3. Use Kyocera 265 W PV modules 4. How many PV modules in series do you need in series for use with the XW MPT 80 charge controller? a. How many 80 A charge controllers are needed?

5. Set up a battery bank with at least 20 kWh of storage. 6. Use Schneider XW inverter(s)

7. What switches and fuses are needed? 8. How many kWh will this produce?

9. Do the wire sizing for each part of the system: a. Consider voltage drop and ampacity for each part b. PV to combiner (180’) c. combiner to charge controller (20’) d. inverter to main circuit box (150’) e. battery to inverters (20’)

10. What size breaker(s) have to be in the main panel? 11. Does the main breaker have to be changed? 12. Make a To Do list for the job
