Example of a VE.Smart Network of a Smart Battery Sense and a solar charger
3.11. Voltage sensing
measures the battery terminal voltage and sends this via Bluetooth using the
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.
3.12. Remote on/off
The solar charger is equipped with a remote on/off terminal. The solar charger can be turned on or off remotely by connecting a
switch to this terminal or by presenting a high signal to the H terminal or a low signal to the L terminal. Alternatively this terminal
can be connected to an external control device, for example a lithium battery management system (BMS).
There a several ways to turn the solar charger on using the remote terminal(s):
• The L and H terminals are interconnected connected via a switch or relay.
• When the voltage on the H terminal is more than 2.9V (up to the battery voltage) via a switch, relay or other external device,
like a battery BMS.
• When the voltage on the L terminal is pulled to battery minus. (<3.5V) via a switch, relay or other external device, like a battery
BMS.
A virtual remote on/off terminal can be created by using the
VE.Direct non inverting remote on/off cable
programmed using the VictronConnect App RX port function settings.
3.13. Programmable relay
The solar charger is equipped with a programmable relay. This relay can be programmed to engage when a certain situation
occurs, such as:
• High PV voltage
• Low or high battery voltage
• High or low temperature
• Float or Equalization active
• Solar charger in an Error state
• Day detection
• Load output
3.14. WireBox
The optional MPPT WireBox is a plastic cover that can be attached to the bottom of the solar charger. It covers the battery and
solar terminals, preventing accidental or inquisitive contact with the battery and PV terminals. It provides an extra level of safety,
and is particularly useful if the solar charger is installed in a general access area.
