Advantages in overview
The voltage converters from the WT-Combi II series provide a pure sine current for people with high claims.
In this case we are talking about a low frequency device with high efficiency.
The power transformation is done with a highly effective troidal transformer. It is only possible to reduce the self usage as drastically through the effective transformator technology so that it´s comparable to high freuquency inverters.
The management and control gets taken care off by a micro-controller in combination with the newest amplifier by MOSFET.
The devices are amongst the most reliable, most durable and economical that can be found world wide.
We only use high quality and no failure-prone components for our products.
The devices from the WT-Combi II series are ideal for proffesionals and for the harsh daily use. Everything has been integrated that is needed by todays standarts- from a charger to an energy saving mode, battery eminence as well as a highly stable, overload protected sine current and even a remote control connection. These inverters can be found by the thousands built in on motor yachts, in caravans and in off grid sytsems. The device guarantees to provide a 230V current dirsuptively at the external mains input as a UPS or charging current feed-in for all connected users and at any time.
The WT-Combi II can provide the double amount of nominal capacity over a short period of time for tarnish currents of motors. Even an overload or a short circuit can´t lead to distruction.
The temperature and load controlled cooler only runs when the temperature inside the inverter really needs to go down.
The devices can even operate other inductive consumers such as induction hobs, fluorescent lamps, fridges, coffee machines and highly sensible things such as televisions, computers, audio systems, espresso machines and similar.
Integrated operable LCD display
The integrated high defintion LCD-Display is used to controll, adjust and show all menu- and configuration points. All data and results can be set and read directly on the device. The inverter is very easy to handle with help of the well structured graphics and symbols. The intuitive three-button- control allows a super easy selection in the menu.
Battery protection undervoltage
There is minimum of battery voltage point that can be reached. As soon as the voltage is below this point, the inverter switches itself off and doesn´t use battery voltage anymore. The switch off point from xx.xV - xxV is adjustable.
An acoustic alarm signal rings as soon as the battery reaches a voltage of 0.5V above the switch off point. The value setting switch off point is xx.xV.
Alarm signal/ operating signal
It can easily be adjustet whether the inverter is supposed to have an acoustic signal when the limit is reached.
Energy saving mode
The inverters have got an automatic load detection and recognition. The sleep mode (automatic load recognition) can be switched on and off with a switch on the device. As soon as the sleep mode is activated and no other active users are connected, the inverter changes from neutral to sleep mode and stays there until an output load ( user more than 35W) gets turned on. The inverter checks every 1-30 seconds whether a 230V device is in need of power. The moment an output load gets recognised, the voltage inverter changes from sleep mode to operating mode and provides the wanted output voltage. This method saves lots of precious battery capacity as the self usage is minimal in sleep mode. The inverter then stays in sleep mode in a standby with a usage of < 2 Watt.
In case that the sleep mode with automatic load recognition is not needed, because some devices e.g. fridges need a continuous power supply, it is easy to deactivate and the inverter runs in neutral. The usage of neutral power always depends on the specific inverter.
Assign and choose priorities
The inverter allows define the primary source of power. There´s always the option to choose between AC eminence and battery eminence. Bei AC With AC- eminence the power gets taken directly from the network, it then gets sent through the inverter to get to the consumer. With battery eminence the consumer gets taken care off with battery voltage until the voltage level is below the selectet load minimum.
Maximum charging power
The charger can be completely turned off at the same time.
Integrated adjustable charger
The integrated charger charges with a IUoUo 4-sep- characteristic always providing a full charge.
All common battery types (lead-acid/ Lithium) can be adjusted.
Over all there are 6 different battery settings for the integrated charger as well as a desulfation funktion and a generell shutdown of the charger that can be chosen from.
With weak mains current or generator power or a peticularly small battery there is always the option to limit the maximum charging power from 100% down to 00%
Small batteries can be charged more gently and the current consumption from the power grid or generator during mains consumption can be reduced while the battery is still charging.
User defined battery
Fast charge current and float voltage can be adjusted at USER. This allows the integrated charger to work with almost all types of batteries. Es The denominations given by the manifacturer can be matched to the specific battery. This allows you to perfectly charge e.g. the LIFEPO4 battery or similar.
Undervoltage switching teshold for battery priority
In case that the priority is set to battery power it is easy to adjust the undervoltage and from where on the power should be taken from the AC input instead of the battery itself, this function is there to preserve the battery.
Return voltage from thr mains to battery
Ist die Batteriespannung durch Aufladung über Solar- oder Windstrom soweit angestiege, dass die Rückkehrspannung erreicht ist, schaltet der Wechselrichter wieder in den Batteriebetrieb um.
Approach of a relay
It is possible to set an undervoltage point from where the relay switches to e.g start a genarator or warning signal (acoustic or visually). Furthermore you can also set the voltage point from where the relay turns it self off.
To improve the user convenience a remote control function is integrated so tht the switch on and off can be controlled more easily.
A wired remote controll is available as an option.
WT-Combi II Geräte have got a built in automatic switch with UPS-function.
As soon as an external power source (shore power, mains power, generator) is availabe, the device switches from inverter to external supply. Troughout the switch over, the frequency gets syncronized and the shift takes place in 10ms (in case the UPS-function is activated) .Therefore all connected users get supplied continuously. Power interruptions, that could possibly lead to a computer crash are completly out of the question.
Quick-Reset/ back to factory setting
If requested the inverter can easily be reset to the factory settings.
