The additional Alpha 24/75 alternator will charge the batteries while
driving/running your engine. This 24 volt 75 amps alternator is designed
to provide maximum output, even at low engine speed (rpm). You will
be able to charge roughly 24 x 75 = 1.8 kWh every hour the engine is
running. This alternator gives you full independence!
Alternator: Alpha 24/75
Batteries: 3 x MLI Ultra 24/5000
Lithium Ion batteries have a high energy density and are perfect for cyclic
applications. They offer savings of up to 70 % in volume and weight, with
three times as many charging cycles (2000 full cycles). The Lithium Ion Ultra
series includes integrated battery monitoring.
The total of AC and DC consumers requires around 6 kWh. For two days
of independency without running the engine you need 12 kWh. Totally
discharging the batteries is not advisable so opt for a maximum of 80 %
discharge for Lithium Ion batteries, i.e. they should provide at least 13.3 kWh.
A battery voltage of 24 V is selected to allow for smaller cable sizes.
The required battery capacity is around 450 Ah.
Three Lithium Ion batteries provide 540 Ah onboard.
3 x safety relay 500 A (mandatory).
3 x fuse holder plus 3 x Class T fuse 225 A.
Charger/inverter: Mass Combi Ultra 24/3500-100
In this case, 450 Ah needs 25 % of the battery capacity for charging power,
so we chose for 100 A charging power via the Mass Combi Ultra. The Combi
Ultra has a battery charger that allows you to safely, quickly and completely
charge two battery banks; starter and service batteries can be separately
charged. Additionally the Mass Combi Ultra can be used to convert the power
for your AC applications, so using everything simultaneously is also possible.
Without grid connection, the solar panels will maintain the batteries.
