Convertidor carregador Mass Combi Ultra 24/3500-100 230 V

This is a complete power management unit designed by Mastervolt. It combines a 3500 W pure-sine inverter, a 100 A main battery charger for 24 V systems, and an integrated solar charge controller with MPPT.

The inverter delivers a continuous power output of 3500 W, even at an ambient temperature of 40 °C. It also has a peak capacity of 7000 W, ideal for starting heavy inductive loads.

Yes, thanks to its 3-stage+ smart charging algorithm, this device is fully compatible with lithium-ion batteries, as well as with lead-acid, gel, and AGM batteries.

Yes, the Ultra range includes a dedicated DC solar input with an integrated MPPT controller. It accepts 30 to 100 V and can handle up to 750 Wp (Watt-peak) of photovoltaic panels.

The Power Assist function automatically compensates for power drops from the AC source (such as a low-amp shore power outlet) by drawing the missing energy from your batteries. This prevents the shore power fuses from tripping.

It has two independent AC inputs (for shore power and a generator) and two AC outputs. The main output (Out-1) provides uninterrupted power, while the secondary output (Out-2) is disabled when no external source is available to preserve battery life.

Yes, the device features a secondary 10 A charge output. This output is configurable for 12 V or 24 V and is specifically designed for maintaining a starter battery or a small secondary battery bank.

No, the Mass Combi Ultra has an IP23 protection rating. It is designed for indoor use only and must be installed in a dry location, protected from direct water spray.

The unit measures 472 mm in height, 318 mm in width, and 178 mm in depth. Its total weight is 15.3 kg.

Yes, up to 10 units can be installed in parallel or in a three-phase configuration to increase available power. This requires connecting the devices via MasterBus and Sync cables and configuring them using the MasterAdjust software.

For this 24V model, it is recommended to use DC cables with a minimum cross-section of 50 mm² and to install an inline fuse rated 175 A as close as possible to the battery bank to ensure system safety and efficiency.

Yes, the integrated inverter delivers a 230V pure sine wave output. This ensures optimal operation without risk of damage to sensitive electrical devices such as computers or televisions.

No, it features Active Optima Cooling, which intelligently regulates the integrated fan speed. This significantly reduces ventilation noise, making it discreet onboard.

The main AC output (Out-1) instantly switches to battery power via its UPS function (uninterruptible power supply). Your critical devices will continue operating without any noticeable interruption.

Yes, the output frequency is configurable for 50 Hz or 60 Hz. This setting can be adjusted easily via the DIP switches integrated into the device or via the MasterBus network.

It operates optimally between -25 °C and 60 °C. Automatic power reduction (derating) is applied when ambient temperature exceeds 40 °C to protect internal components.

Yes, a temperature sensor is supplied with the device. It is highly recommended to connect it to allow the charger to automatically adjust the charging voltage based on the actual temperature of your battery bank.

Yes, the Mass Combi Ultra is fully compatible with the MasterBus communication network. You can connect it to Mastervolt displays or a compatible marine monitoring system for complete control and configuration.

The accepted AC input voltage range is very wide, from 184 to 275 V. This flexibility allows the device to easily adapt to unstable dock networks or voltage variations from generators.

Yes, to ensure a safe and compliant installation with marine electrical standards (such as ABYC), RCDs must be integrated on the AC inputs and AC outputs of the device.
