Why buy a Mastervolt product?
 
Mastervolt products are of the highest technical standard to give the best performance for the leisure boater or commercial user. Each product complies to a number of marine and international standards ensuring premium quality and reliability.
The range of Mastervolt products allow you to design an electrical system around your needs. From the small AC Master inverters and compact IVO Smart battery chargers to the Mass Chargers and Mass Sine inverters for larger systems, and the Mass Combi inverter chargers.
One of the specific advantages of a Mastervolt battery charger is the temperatures at which it can operate at (up to 60°C) allowing you the flexibility to mount it in places other brands would struggle. Their sealed cases and resistance to temperature gives you the option of mounting them out the way in the engine room. For specific technical information and detail on any of the product range visit their website at www.mastervolt.co.uk.
The Mastervolt inverter charger combi unit is very tolerant of poor input voltages and frequencies from your shore power, its output is a pure sinewave at 230vAC so you can be confident that you can run your sensitive equipment through the Mass combi no matter where you are. The inverter-charger combination from Mastervolt is one of the most cost and space effective solutions for a highly effective marine electrical system.

Mastervolt Mass Combi (inverter charger)
Mastervolt 12/2000-100A mass combi
 
Mastervolt 12/2000-100A Mass combi (inverter / charger combination)
The Combi unit offers a very cost effective way of getting a Mastervolt battery charger and Mastervolt inverter at the same time  
The Mass combi is lightweight and compact for its substantial capabilities
The Mass combi's functionality as an inverter allows it to do the following:
 
1) The Combi 's inverter is large enough to run most washing machines, or domestic 230v equipment
2) Act as a hub supplying a 230v ring main for all your onboard 230v needs
3) When plugged into the shore power it will allow 230v on one of its outputs to pass straight through to your 230v appliances without using the inverter and your batteries
4) On its short break output, if your AC shore power fails the inverter will take over immediately so that there is no power interruption to your 230v appliances.
5) If your shore power cannot supply all of your 230v needs then the pure sine wave inverter will switch on to make up the shortfall.
6) The pure sinewave inverter has a continuous output of 2000w, but can supply a surge power of 4000w momentarily to start large equipment.
 
The battery charging feature has two outputs, one at 100A for your domestic battery bank, the other at 5A for your starter battery  
     
  This model of Mastervolt Combi inverter charger comes with a remote control that displays the following:  
 
1) On / off
2) The battery state of charge (in a simple visual gradient 5% - 100%)
3) The DC load on the inverter (in a simple visual gradient 5% - 100%)
4) LED indicators to show the status of the inverter and charger
 
     
  All the Mastervolt Combi units are compatible with numerous models of their remote and battery monitoring systems as part of a professional or large 12v system.
 
     
2 year warranty  
All connections are internal (inside the casing) offering safety, reliability and performance  
An LED display and switch on the front of the unit show exactly what's happening and allow control to switch the unit ON/OFF and on to CHARGER ONLY.

Three separate battery banks can be monitored simultaneously.
The shunt is included for monitoring your main battery bank extremely accurately (no other shunts are needed for the other banks)  
The BTM battery monitor also stores historical information concerning battery use, so you can interrogate it to find out exactly how the electrical system on your boat is performing.  
There are various mounting options for this unit, supplied as standard it needs to be countersunk into a bulkhead.
