3.8 Battery charging information

The charge controller starts a new charge cycle every morning, when the sun starts shining.
User defined algorithm:
The default settings can be modified with Bluetooth or via VE.Direct.
Lead-acid batteries: default method to determine length and end of absorption
The charging algorithm behaviour of MPPTs differs from AC connected battery chargers.
Please read this section of the manual carefully to understand MPPT behaviour, and always
follow the recommendations of your battery manufacturer.
By default, the absorption time is determined on idle battery voltage at the start of each day
based on the following table:
Battery voltage Vb (@start-up)
Vb < 11,9V
11,9V < Vb < 12,2V
12,2V < Vb < 12,6V
Vb > 12,6V
(12V values, adjust for 24V))
Default absorption voltage: 14,4V
Default float voltage: 13,8V
The absorption time counter starts once switched from bulk to absorption.
The MPPT Solar Chargers will also end absorption and switch to float when the battery
current drops below a low current threshold limit, the 'tail current'.
The default tail current value value is 1A.
For models with a load output the current on the battery terminals is used; and for the larger
models; the current on the output terminals is used.
The default settings (voltages, absorption time multiplier and tail current) can be modified
with the Victronconnect app via or via VE.Direct.
There are two exceptions to normal operation:
1. When used in an ESS system; the solar charger algorithm is disabled; and instead it
follows the curve as mandated by the inverter/charger.
2. For CAN-bus Lithium batteries, like BYD, the battery tells the system, including the solar
charger, what charge voltage to use. This Charge Voltage Limit (CVL) is for some
batteries even dynamic; changes over time; based on for example maximum cell
voltage in the pack and other parameters.
