ChargeMaster Plus
The Mastervolt ChargeMaster Plus is a universal battery charger for yachts, motorhomes, and vehicles, capable of charging multiple battery banks simultaneously, thus eliminating the need for additional chargers, isolation diodes, and VSR relays. philippi, as a Mastervolt system partner, supplies the ChargeMaster Plus in current ratings of 40, 60, 75, and 100 A and integrates it into philippi P-Bus systems with PSL/PSM3 monitors via the CMB interface.
- Master bus compatible
- for professional use
In detail. ChargeMaster Plus.
Your Advantages with the ChargeMaster Plus
- One device instead of three: charger, DC-DC converter, and automatic voltage sensitive relay (VSR) function in one compact housing – less installation space, less wiring.
- Charges up to three battery banks of different types (lithium-ion, gel, AGM) simultaneously and independently.
- Very wide AC input range (80–275 V, 35–70 Hz) ensures reliable operation on shore power worldwide.
- 3-step+ charging characteristic automatically detects the state of charge, thus protecting the battery throughout its lifespan.
- Directly networkable with displays, shunts, and other system components via CAN-based MasterBus.
Compact Charging Solution for Complex Onboard Electrical Systems
The Mastervolt ChargeMaster Plus was developed for onboard electrical systems where multiple battery banks of different chemistries – such as a lithium-ion service battery and an AGM starter battery – need to be charged reliably. Instead of multiple individual devices, the ChargeMaster Plus combines charger, DC-DC converter, and isolation relay functions in one housing, significantly reducing the complexity and cost of onboard electrical system installation. philippi uses the ChargeMaster Plus in both marine and off-road/camper applications where multiple consumer circuits are supplied with different battery types.
Via the philippi CMB interface (order no. 0 7100 0030), the ChargeMaster Plus can be integrated into an existing P-Bus system: charging currents, battery voltages, and operating status are then clearly displayed on the PSL or PSM3 P-Bus monitors. As a Mastervolt System Partner, philippi supplies the ChargeMaster Plus together with the appropriate monitors and can also handle the complete system design upon request.
Technical Data
Source of technical data: official Mastervolt product data sheets (mastervolt.com). Note: The last digits of the philippi SKU differ slightly from the order number documented on mastervolt.com (e.g., SKU M44310755 vs. Mastervolt order number 44310750) – it is the same series/power class.
Compatibility with the philippi P-Bus System
According to the philippi catalog ("Mastervolt System Solutions"), the ChargeMaster Plus is among the devices that can be connected to the philippi P-Bus via the CMB interface (order no. 0 7100 0030). Charging currents and operating status, along with other CMB-compatible Mastervolt devices such as MASS Combi Ultra, CombiMaster, ChargeMaster, Solar ChargeMaster, MAC Plus, MasterShunt, and MLI Lithium batteries, can be displayed on the PSL and PSM3 system monitors.

Frequently asked questions. Answered briefly.
Can the ChargeMaster Plus charge multiple battery types simultaneously?
Yes, the ChargeMaster Plus can charge lithium-ion, gel, and AGM batteries in parallel and independently, even in different bank sizes.
What current rating do I need for my onboard electrical system?
This depends on the battery capacity and desired charging time. philippi will be happy to advise you on the appropriate variant between 40 and 100 A for your 12 V or 24 V system.
Can I integrate the ChargeMaster Plus into my philippi P-Bus system?
Yes, via the CMB interface (order no. 0 7100 0030), the ChargeMaster Plus is connected to the P-Bus and displayed on the PSL/PSM3 monitors.
Does the ChargeMaster Plus replace a battery isolation relay (VSR)?
Yes, the VSR function and a DC-DC converter are already integrated, eliminating the need for separate isolation diodes or isolation relays.
Does philippi handle system planning?
Yes, as a Mastervolt System Partner, philippi designs your individual charging system around the ChargeMaster Plus and supports you during commissioning.
