UPDATE read here for important information on how to wire up charging devices !
On the roof of the unit a set of high quality, powerful monocrystalline 24V Victron solar panels with a theoretical the output, of 0.63kW are installed. Coupled with a smart MPPT solar controller this ensures a maximum current output, in order to fully capitalise on the energy supply potential of the solar panels.
Besides the abundant capacity of the solar panel system, power can also be generated by the truck’s alternator. The alternator thus can function as a back-up power generation source. The standard Steyr alternator was upgraded from 35A to theoretically 55A, excluding the trucks energy usage at that moment, all running at 24V DC automatically when the truck is running. Smart regulation of the Victron Citrix-CT device ensures that this is done automatically.
The split charge cable harness is the only cable connecting the vehicle chassis to the unit. This connection can also be used in reverse to start the truck utilising the domestic leisure batteries should the truck batteries fail for some reason.
Inverter & charging
The nominal voltage of the battery banks is 24V DC. Due to multiple inverters, there is also a stabilised 12V DC (not in use right now), 24V DC and 230V AC network. The 230V AC is generated by a Victron Multiplus, 1,2kW inverter, enabling us to run the laptop, coffee maker and other appliances. The programmed inverter doubles as a 25A-24V DC charging device for 230V AC grid power. Matching the 220Ah capacity to it’s charging cappacity ratio.
