3.7 Connecting an inverter
The load output can be used to supply DC loads and simultaneously to control an inverter.
The Victron inverters model Phoenix 12/800, 24/800, 12/1200 and 24/1200 can be
controlled by connecting the left side connection of the inverter remote control directly to the
solar charger load output (see figure 4).
For the Victron inverters model Phoenix 12/180, 24/180, 12/350, 24/350, the Phoenix
Inverter C models and the MultiPlus C models an interface cable is needed (MPPT 70/15 to
inverter remote on-off cable, article number ASS030550100, see figure 5).
3.8 Battery charging information
The charge controller starts a new charge cycle every morning, when the sun starts shining.
The maximum duration of the absorption period is determined by the battery voltage
measured just before the solar charger starts up in the morning:
Battery voltage Vb (@start-up)
23,8V < Vb < 24,4V
24,4V < Vb < 25,2V
(divide voltages by 2 for a 12V system)
If the absorption period is interrupted due to a cloud or due to a power hungry load, the
absorption process will resume when absorption voltage is reached again later that day,
until the absorption period has been completed.
The absorption period also ends when the output current of the solar charger drops to less
than 1 Amp, not because of low solar array output but because the battery is fully charged
(tail current cut off).
This algorithm prevents over charge of the battery due to daily absorption charging when
the system operates without load or with a small load.
3.8.1. Automatic equalization
Automatic equalization is default set to 'OFF'. With the Victron Connect app (see sect 3.8)
this setting can be configured with a number between 1 (every day) and 250 (once every
250 days). When automatic equalization is active, the absorption charge will be followed by
a voltage limited constant current period. The current is limited to 8% of the bulk current for
the factory default battery type, and to 25% of the bulk current for a user defined battery
type. The bulk current is the rated charger current unless a lower maximum current setting
has been chosen.
When using the factory default battery type, automatic equalization ends when the voltage
limit 16.2V / 32.4V has been reached, or after t = (absorption time)/8, whichever comes first.
For the user defined battery type automatic equalization ends after t = (absorption time)/2.
