Care and maintenance of the LiFePo battery system:
•
The state of charge of the battery should be checked regularly; recharge the battery if necessary.
•
Check the pole terminals for a secure fit.
•
If the motorhome is out of use for a long period of time, you must make sure that the battery is rechar-
ged to 50% -80% at regular intervals (every 2-3 months). If a 230V external connection is available,
the charging devices generally take over the recharging automatically. If the vehicle is outdoors, this
function is usually also performed by the solar system.
Avoid frequent discharges below 30%. The same applies to LiFePo batteries, the greater the depth of di-
scharge, the shorter the lifespan of the batteries. However, these batteries do not have to be fully charged
or recharged permanently and are usable in a partially charged state between 30% and 100%.
To prevent damage to the LiFePo battery, there are several protective devices:
•
At very low temperatures below 0°C, the performance of the charging systems is reduced and, if
necessary, completely interrupted from -20°C. This also applies to very high temperatures above
50°C. In both cases, charging starts again automatically when the battery warms up or cools down
again.
•
Battery capacity warning:
Please note the battery capacity indicator on your battery computer. If the usable capacity falls below
30%, a flashing display should indicate that less than 30% of the battery capacity can still be used
and should be recharged if necessary.
Automatic battery shutdown:
Deep discharge, permanently too high currents, too high temperatures, as well as incorrect charging voltages can lead
to the automatic switching off of the LiFePo battery for its protection!
If the switch-off criterion no longer exists or charging takes place, the battery switches on again auto-
matically and can be used normally. Please note that specific settings may then be required in your
on-board electronics
The on-board battery must be replaced with the same type and specification as the originally installed on-board battery,
or as specified by the manufacturer. When expanding the existing LiFePo battery with an additional battery, it is essential
that both batteries are charged 100% independently before they are connected in parallel!
Solar module:
The 2 installed solar modules are BlackLine solar modules with very high efficiency MultiCell technology. The solar mo-
dules have a total output of 200Wp. The solar panels are located on the vehicle roof and convert sunlight into electrical
energy. The energy obtained in this way is fed directly into the 12-volt electrical system, and the on-board battery is
charged if there is an excess. The solar controller takes over the distribution of the solar power.
Maintenance and care of the solar modules:
•
The solar cells are protected by a hardened glass plate. The panel is waterproof and weatherproof. So-
lar cells must be clean in order to maintain their performance. Therefore, you should clean the glass
plate of the module with a damp cloth and a little washing-up liquid every 4 weeks.
•
In dusty environments, the solar panel should be cleaned more often.
•
In winter, the panel must be kept free of snow, as covered solar cells cannot supply electricity.
Solar controller:
The solar controller installed is an MT-230-PP (Power-Plus) controller, which is designed for a total solar power of up to
230Wp. The controller takes over the control of the current coming from the solar panels into the 12V power network
and the charging of the on-board batteries.
Operating indicators:
•
“weak” (yellow):
Lights up: Undervoltage in on-board batteries. The batteries should be recharged as quickly as possible.
•
“Standby” (green):
Flashes: The controller is in standby when no solar power is flowing (at night).
•
“Laden/ Charging” (green):
Lights up: Brightness from a slight glow to full brightness indicates the charging current.
•
Off
Not enough solar energy available.
