Understanding the Mastervolt EasyView 5 Screen
Article Objective:
In this article, you will learn how to use the Mastervolt EasyView 5 screen to monitor and adjust your Mastervolt lithium battery system.
Affected Units:
Vandoit vans with a Mastervolt lithium battery system
Background:
The Mastervolt system consists of more than just the lithium batteries. It also includes the Combimaster inverter/charger and the MacPlus (the device that allows the battery system to charge from the vehicle's alternator). The Mastervolt screen, located above the slider door of the van, provides data on these three main components of the Mastervolt system.
What is on my Mastervolt screen?
The home button wakes up/turns on the Mastervolt EasyView 5 screen. A quick tap wakes up the screen, and holding it brings up Lock Screen setting.
The page indicator shows where, of the screen's total pages, the page you are currently viewing is ordered.
The widgets display information about the batteries, Combimaster, or MacPlus. These are labeled in blue at the top of each widget as Primary, Inverter, and Alternator, respectively.
The edit button allows you to add and edit widgets on the pages.
The settings button opens the EasyView 5 settings page.
The system button opens the system page, which displays a list of all connected devices (i.e. batteries, Combimaster, and MacPlus) and all of their data.
What does each widget mean?
1. Primary state of charge: Indicates the lithium battery bank's current charge capacity.
2. Primary time remaining: Provides an estimate of how much time the Mastervolt system will supply power to the devices that are currently operating in the van, based on the draw at that exact moment. A display of --:--:-- indicates that the van is plugged into shore power and/or charging is outrunning power draw, resulting in the system having "infinite" time remaining, so to speak.
3. Primary current: Shows the sum total of all charge and discharge on the system. The amperage will indicate the offset of system usage (as a negative number) or the amount charging the system (a positive number).
4. Inverter on/off: Allows you to turn the inverter on and off. The inverter is what allows power to flow to AC-powered devices, or anything plugged into wall outlets.
NOTE: Being plugged into shore power will still provide AC power to the outlets in your van, regardless of turning the inverter on.
5. Inverter device state: The CombiMaster is a 3-in-one device: The inverter part of the CombiMaster converts incoming DC current to AC current that powers many of the van's devices--namely, those devices plugged into the van's 120 volt wall outlets, continuously pulling up to 2000 watts of power. The charge controller part of the CombiMaster detects when shore power has been plugged in and automatically begins charging the batteries. If shore power is unplugged, the charge controller switches back to inverting power. Lastly, the CombiMaster has an AC transfer switch, which allows the AC-powered devices to be powered directly from shore power when it is plugged in, as opposed to inverting the battery power. This widget indicates which function the CombiMaster is currently performing: inverting power to the AC-powered devices, transferring a charge to the batteries, or transferring power from shore power directly to the AC-powered devices.
6. Inverter output power: Displays the amount of power (in watts) the inverter is currently sending to AC-powered devices in the van. These devices can receive up to 2000 of total watts simultaneously.
7. Inverter AC IN limit: Displays how much incoming amperage the system can receive. This is set at 13 amps from the factory to help avoid overloading the circuit the van's shore power is plugged into (i.e. in a house, building, or campsite).
8. Inverter input current: Displays how much amperage is actually coming in, depending on how full the battery system currently is.
9. Alternator input voltage: Displays the Ford car battery voltage. This is a beneficial way to check the vehicle's battery health if the car has not been driven in a few days.
11. Alternator output current: Displays the rate of charge to the Mastervolt system from the alternator (at a rate of up to 50 amps per MacPlus).
12. Alternator charge state: Indicates whether the Mastervolt system is currently receiving a charge from the alternator or not (i.e. whether the van engine is on or off) and what state of charge it is currently in (bulk, absorb, or float).
The Vandoit team has programmed the EasyView 5 screen to display these widgets in order to provide you with the best information on your Mastervolt lithium system. Please do not delete any widgets unless Vandoit has instructed you to do so.
How do I operate the screen?
1. Place your thumb over the Home Button to "wake up" the screen. (Sometimes, you may need to tap elsewhere on the screen to wake it up.)
2. The small white circles at the bottom of the screen indicate which page you are on. To navigate to another page, swipe or tap at the bottom left or bottom right of the screen.
3. If you find your screen is not working properly, please see this Knowledge Base article to troubleshoot: https://vandoit.zohodesk.com/portal/en/kb/articles/mastervolt-screen-not-working
What can I adjust?
1. You can use the Inverter on/off widget to send power to the van's wall outlets, or to turn that power off.
2. You can turn the audio on or off for alerts.
3. Widgets can be moved/added, but this is not recommended to avoid accidental deletion of a widget.
4. The backlight time can be adjusted.
5. A password can be created or changed.
In general, it is best not to adjust any other parts of the Mastervolt system unless a Vandoit team member has instructed you to do so.
What do I do with alert messages?
When an alert is active in the Mastervolt system, a red triangle icon with an exclamation point will appear on the screen. Please see the information below on what to do with these alert messages. If you have an alert message, please contact Vandoit and provide photos of the message. Some alerts cannot be cleared until certain parameters have been met. For example, the low battery alert will not clear until the battery has been charged to a healthy level.
