Safety and installation location
Installation must be carried out by an electrician or professional installer, and on pleasure craft in accordance with ISO 13297. Never work on the unit while it is live: switch off all energy sources, disconnect the batteries using the battery isolator switches, and switch off or isolate chargers and alternators.
- The PE terminal must be earthed and connected before any other connection. Before switching on, the housing is closed with the supplied screw.
- Mount the unit on a vertical wall. Leave 150 mm of clearance around the charger; even in extreme conditions the air temperature at the inlet must be below 65 °C. The hot air must be able to escape on both sides.
- Do not place any objects on or against the charger, and do not install it near a heat source, flammable materials, liquids or gases. Keep moisture, salt and dust away.
- Do not drill into or modify the housing.
- A battery switch belongs as close as possible to the batteries. The manual requires 30 mA residual current protection on the AC side (recommendation NFC 15-100).
Mounting: 4 round-head screws M5 (head diameter under 10 mm), mounting spacing 272 × 170 mm, housing 289 × 195 × 106 mm.
Wiring diagram and cabling


AC side: The mains cable is plugged into the Winsta mains socket on the unit. The charger operates on single-phase mains from 90 to 265 V AC and 47 to 65 Hz. It is in operation as soon as mains voltage is present and switches off 20 seconds after the mains voltage is lost. When using a generator, first check compatibility (power, voltage, overvoltage, frequency); the charger's AC input should be switched off when the generator is started. Damage caused by overvoltage is excluded from the warranty.
Battery side: Disconnect the batteries before plugging in. Beforehand, check polarity and voltage with a calibrated voltmeter and make sure that the charger and the battery banks match in voltage and current. The supplied Phoenix Contact connector is assigned from left to right:
| Terminal | Connection |
|---|---|
| -BAT | Negative of the battery system |
| +BAT E | Positive, starter battery |
| +BAT 1 | Positive, battery bank 1 |
| +BAT 2 | Positive, battery bank 2 |
| +BAT 3 | Positive, battery bank 3 (see note) |
Note on +BAT 3: The technical data table lists four outputs for the ACE 24/30, including +BAT 3. The cabling section of the manual, however, mentions +BAT 3 only for the models 12/44, 12/64, 24/24 and 24/34. Check the terminals on your unit or ask us.
The maximum cable cross-section for the output of the ACE 24/30 is 16 mm². Unused outputs remain unconnected. Each output can deliver the rated current.
Avoiding interference: Keep at least 2 m away from sensitive radio equipment, route the AC mains cable separately from battery charging cables and at least 200 mm from data and control cables, and do not connect any other devices to the AC cable.
Settings with the push button
The charger is configured with the "P" push button or via the P-BUS. A long press (1 to 2 seconds) switches to programming mode: the ON LED (LED 1) lights up blue, the charging phase LED (LED 2) white. In programming mode, the number of flashes of the ON LED indicates the programming field, and the number of flashes of the charging phase LED indicates the value. A steady white LED means value 0. A short press increases the value by one; a long press saves and jumps to the next programming field. After saving, both LEDs flash blue. If you want to restore the state before the changes, interrupt the power supply for 60 seconds: settings are only saved when you leave programming field 3.
Programming field 1: Battery type (voltages for 24 V)
| Value | Battery type | Floating | Boost | max. boost | max. absorption |
|---|---|---|---|---|---|
| 0 | flooded, free electrolyte | 26.8 V | 28.2 V | 2 h | 4 h |
| 1 (factory) | classic sealed (sealed lead) | 27.6 V | 28.8 V | 2 h | 4 h |
| 2 | Gel | 27.6 V | 28.8 V | 2 h | 4 h |
| 3 | AGM (refresh not recommended for all AGM types) | 27.2 V | 28.8 V | 2 h | 4 h |
| 4 | Spiral cells | 27.2 V | 28.8 V | 2 h | 4 h |
| 5 | Lead-calcium-tin | 28.8 V | 30.2 V | 2 h | 4 h |
| 6 | Winter storage/standby, sealed battery | 26.8 V | 26.8 V | 0 h | 0 h |
| 7 | Power supply mode | 24.0 V | 24.0 V | 0 h | 0 h |
| 8 | flooded SP | 26.4 V | 29.6 V | 2 h | 4 h |
| 9 | LiFePO4 with BMS | 27.6 V | 28.8 V | 6 h | 1 h |
| 10 | Stormline | 27.4 V | 29.0 V | 2 h | 6 h |
| 11, 12 | specific | 24.0 V | 24.0 V | 0 h | 0 h |
| 13 / 14 / 15 | 13 adjustable via Bluetooth, 14 adjustable via CAN bus, 15 not used | ||||
The voltages apply at +BAT 1, +BAT 2, +BAT 3 and +BAT E at 10 % of the rated current (tolerance ±1 %). When switching on, the number of flashes of the charging phase LED shows which curve is currently in use. After 15, the value jumps back to 0.
Programming field 2: Refresh and boost
| Value | Refresh | Boost |
|---|---|---|
| 0 | off | off |
| 1 (factory) | off | on |
| 2 | on | off |
| 3 | on | on |
Boost (IUoU curve) charges faster and is time-controlled; the changeover to the floating phase takes place at a battery current below 20 % of the rated current (below 12 % for LiFePO4 with BMS). Boost off results in a pure IU curve for maintenance charging, which is only suitable for stationary batteries in continuous operation. Refresh periodically applies a voltage increase to maintain the battery and prevent sulfation.
Programming field 3: CAN bus protocol
| Value | Protocol |
|---|---|
| 1 | Cristec |
| 2 | Multibloc |
| 3 (factory) | philippi P-BUS |
philippi P-BUS is preset and should not be changed. After a long press, the charger returns to normal operation.
Factory setting: sealed lead, boost on, refresh off, standby off. This compromise charges flooded lead, gel, AGM, spiral cell and LiFePO4 batteries with BMS satisfactorily. For special batteries, have an installer set the values according to the battery manufacturer's specifications. philippi is not liable for battery damage or incorrect charging.
Temperature sensor, OTD sensor and P-BUS
- Temperature compensation: The temperature sensor adjusts the absorption and floating voltage to the temperature of the battery compartment, at -18 mV/°C for 12 V models and -36 mV/°C for 24 V models. No compensation is applied for winter storage/standby, power supply mode and LiFePO4 with BMS.
- OTD sensor (optional): The digital input stops charging and triggers an alarm if it remains open. It can also be used with a relay contact as a remote on/off switch. At the factory it is disabled by a jumper: connect the sensor on the front and set jumper JP3 to position 1-2.
- P-BUS: For this, plug the optional ACE-T-KABEL HPO (5 0411 1162) into one of the two six-pin sockets; the second remains free. Jumpers JP1 and JP2 stay in the position shown, and the four DIP switches stay at 0000. Display and settings are possible with the monitors P-BUS System Monitor PSL and P-BUS System Monitor PSM3 (the manual refers to PSM and PSL).
Charging curve
With boost on, the unit delivers a five-stage IUoU curve with automatic weekly recycling: boost, absorption, floating, refresh, reboost.
- Boost: starts after switch-on when the battery is discharged; the maximum current flows.
- Absorption: begins when the boost voltage is reached; the current falls. Boost and absorption together last at most T Boost plus T Abs.
- Floating: begins after T Abs or at a current below 20 % of the rated current; the voltage drops to the floating value.
- Refresh: automatic weekly cycle after a complete charging cycle, a time-controlled voltage step every 7 days, even when refresh is switched off.
- Reboost: new cycle with boost if connected DC loads require it, only within a defined period.
With boost off, the unit delivers a single-stage IU curve with constant voltage. Charging then takes longer.
LED indicators and troubleshooting
Two LEDs on the front show the status. When the unit saves a new configuration, both LEDs flash blue three times.
| LED | Indication | Meaning |
|---|---|---|
| LED 1 "ON" | green, steady | Charger is powered |
| LED 1 "ON" | green, flashing | Standby mode |
| LED 1 "ON" | blue, flashing | Programming |
| LED 1 "ON" | off | Fault: AC mains missing or damaged, input fuse blown or internal malfunction. Check the AC supply cable and input fuse, otherwise get in touch. |
| LED 2 "Charging Phase" | yellow, flashing | Boost phase |
| LED 2 "Charging Phase" | yellow, steady | Absorption phase |
| LED 2 "Charging Phase" | green, steady | Floating phase |
| LED 2 "Charging Phase" | green, flashing | Refresh phase |
| LED 2 "Charging Phase" | off | Output voltage off |
| LED 2 "Charging Phase" | red, flashing pattern | Depending on the pattern: OTD fault, output fuse blown, temperature range or no output voltage (for the patterns see page 19 of the PDF manual (German)) |
| LED 2 "Charging Phase" | red, steady | Other faults |
Output fuses may only be replaced with suitable fuses (Bussmann/Eaton ATM 20, ATM 30 or ATM 15; for the ACE 24/30 two 30 A/32 V fuses). For any repair, contact an authorised dealer or philippi; unauthorised repairs void the warranty.
Maintenance, repair and disposal
- For maintenance and repair, disconnect the charger from the AC mains and from the batteries.
- In dusty environments, vacuum regularly, because dust impairs heat dissipation.
- Check the state of charge of the batteries every 3 months and check nuts and screws for tightness once a year.
- Dispose of via the local collection points for waste electrical and electronic equipment.
According to the manual, the warranty is 24 months. More on this: Warranty and repair.
