Chapter 10
Off-Grid PV System with DC and AC Loads
10.1 Introduction
This laboratory builds on Chapter 9, which dealt with an off-grid system with DC-only loads. This laboratory can be skipped without affecting the rest of the laboratory sequence. In this laboratory we upgrade certain subsystems as well as add others:
- Adding a 1000 W 120 VAC inverter for AC loads
- Upgrading from 200 Wp to 400 Wp PV subsystem
- Upgrading from a single 12 V/258 Ah battery to two such batteries
- 2000 W 120 V AC gas-powered generator
These additional equipment additions and upgrades in turn allow the following performance improvements:
- Up to 1 kW of 120 VAC equipment loads
- Twice the stored battery energy
- Twice the photovoltaic power (and energy) production
- Ability ...
