REPLENISHMENT POWER
FROM ENGINE ALTERNATOR
BACKUP FOR SOLAR ON POOR DAY
This article is designed to give choices available to the reader from engine power using either the vehicle supplied alternator or adding a second high power alternator.
PRIMARY POWER WHEN TOURING
After camping overnight and driving till midday to next campsite, the on-engine alternator will be a primary source of power. The energy delivered is measured in a 3 hour drive with and without solar production.
BACKUP POWER WHEN CAMPING
After finding the perfect campsite, the on-engine alternator will be a backup source of power. In poor weather, or if touring southern Victoria or tasmania, back-up power is essential. The energy delivered is measured at an idle of 500 rpm for 1 hour with and without solar production.
