Extend the off grid calculation workbook by adding a load parameters sheet with loads: lighting, refrigerator, computer, vacuum cleaner, microwave, ceiling fans, including power, hours, and total energy.

Add pv components to the system sheet, enter mppt current and voltage, isc, voc, noct, and dimensions, then configure battery, inverter, and charger parameters for off-grid calculation.

Explore off grid calculations for a 12-volt battery system, including series battery counts, dod, and reserve days. Size the pv array with panels and inverters using energy and safety factors.

Explore underground cables' construction—from copper or aluminum conductors and conductor screens to BVRC and XLB insulation, armor, and bedding—and voltage classes from low tension to extra high.

Explore low voltage cable sizing and selection by evaluating application, insulation type (xlpe vs pvc) and conductor (aluminium vs copper), environmental derating, voltage drop limits, and prospective fault current calculations.

Size the circuit breaker and select a buried wet soil 2.5 mm four-core cable for the residential panel, applying derating, voltage drop checks, and short-circuit capacity.

Explore fuse protection in a BSV PV system, covering fuse sizing per NEC 690.9 B, the 80% rating rule, and derating for ambient temperature to protect PV conductors.

Understand surge protection devices that shunt overvoltage to ground to protect loads from lightning, and learn IEC 61643-11 parameters for type 1 or 2 SPD selection.

select circuit breakers by voltage rating, nominal current, and magnetic current, using UL 489, 125 percent rule, and selectivity concepts from current to logic with pilot interlocks.
