DC systems.
DC systems supply the 12, 24 or 48 V on-board system with energy: shore power chargers, high-output alternators with regulators, charging boosters, DC/DC converters, inverters, solar equipment and lithium batteries. In this category you will find devices from philippi, Balmar, Studer, Mastervolt, Alfatronix and Sunware for yachts, motorhomes and vehicles.

DC systems for boats and vehicles: charging, converting, storing
In short: Match every charging source to the battery bank. For the ACE chargers, philippi specifies a recommended battery capacity, for example 100 to 200 Ah for the ACE 24/25 and 300 to 900 Ah for the ACE 12/90.

Frequently asked questions. Answered briefly.
Which ACE charger suits my battery bank?
philippi specifies a recommended battery capacity for each ACE model: 100 to 200 Ah for the ACE 24/25, 150 to 300 Ah for the ACE 24/30 and 300 to 900 Ah for the ACE 12/90. The ACE 12/44 and ACE 12/64 models charge up to four battery groups at the same time, for example starter, service and bow thruster batteries.
Which ACE chargers work without a fan?
The ACE 12/30, ACE 12/44, ACE 12/64 and ACE 24/25 models work without a fan and therefore without fan noise, which is pleasant especially at night near the berths. The ACE 24/30 has a fan that only switches on when needed and can be set to a quieter mode with reduced output via the remote control panel.
Charging booster or DC/DC converter, what is the difference?
A charging booster charges the service battery from the alternator while under way. A DC/DC converter supplies loads with a voltage different from that of the on-board system; the Alfatronix DD 48/12, for example, reduces 48 V to 13.6 V for 12 V loads. The DDi models also have a galvanically isolated output.
Inverter or inverter/charger?
An inverter such as the DCW series or the Studer AJ models generates a 230 V sine wave voltage from the on-board battery for loads independent of the shore supply. The Studer XTM and XTH inverter/chargers combine inverter and battery charger in one device and are suitable for systems with high energy demand.
