Page 10: Temperature Sensing
MPPT solar charger manual 3.9. Temperature sensing Temperature sensing allows for temperature compensated charging. The absorption and float charge voltages are adjusted based on either the battery temperature (accessory needed) or otherwise on the solar charger internal temperature. Temperature compensated battery charging is needed when charging lead-acid batteries in hot or cold environments. The temperature compensation can be enabled or disabled in the solar charger settings and the amount of compensation, the compensation coefficient (mV/°C), is adjustable. -
Page 11: Voltage Sensing
MPPT solar charger manual 3.10. Voltage sensing An optional Smart Battery Sense battery monitor measures the battery terminal voltage and sends this via Bluetooth using the VE.Smart [28] network to the solar charger. If the battery voltage is less than the solar charge voltage, the solar charger will increase its charge voltage to compensate for voltage losses. -

This offset voltage is used to determine when the float stage stops and the bulk stage starts again, i.e. the charge cycle resets and starts at first charge stage again. An example: If the re-bulk offset is set at 0.1V and the float voltage at 13.8V, the charge cycle will restart once the battery voltage drops below 13.7V (13.8 minus 0.1) for one minute.

MPPT solar charger manual Absorption During this stage the solar charger switches to the constant voltage mode, where a pre-set absorption voltage is applied. When the charge current decreases below 2A or if the pre-set absorption time has elapsed, the battery is fully charged and the solar charger will enter the Float stage. -
Page 41: Victronconnect Error Reporting
MPPT solar charger manual You can use the charge times to see if the PV array is properly sized for your requirements. A system which never reaches the float stage may need more panels. Or perhaps the load should be reduced?

Page 48: Pv Voltage Too High
MPPT solar charger manual Compare the two voltages. If the battery voltage and the controller voltage are not the same, then investigate why this is. Follow the path from the controller to the battery to investigate what could be the cause. Battery supply check Check and verify that all cabling is connected correctly, and that no wiring mistakes have been made. -
Page 49: Batteries Are Undercharged

Page 51: Wrong Temperature Compensation Setting
MPPT solar charger manual To investigate look at the history tab in the VictronConnect app. The histogram displays how long the batteries have been charged in the Bulk, Absorption and Float stage each day, for the last 30 days. If you click on one of the histogram columns you will see a breakdown of the charge stages. -
Page 52: Battery Charge Voltages Too High
MPPT solar charger manual The solar charger automatically detects the battery voltage on first install and after the self-detection is disabled. This can become a problem if a solar charger that came out of a 24V system is now used in an 12V system. In that scenario it will not detect that the system has changed and will keep charging with 24V battery charge voltages, while the connected battery is a 12V battery and the 12V battery will be overcharged. -
Page 53: Solar Issues
MPPT solar charger manual To check if the battery is close to its cycle life: Find out how many charge and discharge cycles the battery has been subjected to. Battery lifetime correlates to the number of cycles. Check how deep the battery has been discharge on average. A battery will last for less cycles if deeply discharged, compared to more cycles if discharged less deep. -

Page 61: Charger Error Code Overview
MPPT solar charger manual 11.2. Charger error code overview This overview lists all possible error codes that can be generated by a solar charger or AC charger. The error codes are displayed on the charger display, remote display or via a connected GX device. Note that not all of these errors might apply to your charger model. - Page 62 MPPT solar charger manual Power terminals overheated, check wiring, including the wiring type and type of strands, and/or fasten bolts if possible. This error will auto-reset. Error 28 - Power stage issue This error will not auto-reset. Disconnect all wires, and then reconnect all wires. If the error persists the charger is probably faulty. Note that this error was introduced in v1.36.
- Page 63 MPPT solar charger manual This error only shows when there is solar power available and thus the charger is ready to initiate charging. It does not show at night. In case there is a permanent problem, the error will raise in the morning and clear at night, and so forth. Check the connection between the charger and the BMS.
