The Combiner 100 is a voltage-sensing relay (13.3 volts) which connects two
batteries together when either is receiving a charge. When the charging ceases,
the relay opens so that each battery operates independently. Supplemental
battery banks can be added by using an additional combiner for each bank.

This combiner is suitable for installations with alternators up to 100 amps
with one battery in each bank. Larger installations should consider using the 160 Amp.
