Hybrid Inverter WS-TwinPeak TP3k24 Plus MPPT

Combined Sine Inverter WS-TwinPeak 3000 W 24 V Plus by WATTSTUNDE for Solar Off-Grid Systems

Become independent of the public power grid - with the TwinPeak off-grid inverter!
The new voltage converter from the TwinPeak series is a compact combination device that unites a variety of functions in one unit:
 

1. Inverter with pure sine wave for solar off-grid systems
2. Battery charger
3. Solar charge controller
4. Shore power connection

The TwinPeak is the ideal solution for realizing a fully functional solar off-grid system: By connecting PV modules (maximum 1500 Wp), the connected battery can be charged anytime and anywhere.
In addition to reliably operating 24 V DC consumers, the powerful combined unit also allows 230 V AC consumers to be connected. It generates a pure sine wave voltage to power your household appliances.
The device is rounded off by the shore power connection: Energy can be fed into your self-sufficient system from an external source such as a grid connection. The TwinPeak is particularly suitable for small solar off-grid systems in remote cabins or small garden sheds that are to be operated independently of the grid.

Important!: It is not suitable for campers or boats. It must not be installed in vehicles!

The TwinPeak device is characterized by the following:

• Powerful off-grid inverter: sine inverter, solar charge controller, battery charger in one
• True sine wave voltage for 230 V consumers (max. 3000 W continuous power)
• Powerful 60 A MPPT solar charge controller integrated: Connect solar panels with up to 1500 Wp output
• Integrated 30 A 24 V battery charger for automatic battery charging
• Shore power connection: if required, power can be fed from the grid (transfer switch with 10 ms switching time integrated)
• Variety of setting options: Priorities, energy-saving mode, etc. - almost all parameters can be freely adjusted. Further information can be found in the manual
• LCD display: System information quickly and easily readable (battery and PV as well as consumers)
• Suitable for AGM/Gel batteries (lead-acid batteries), LiFePO4 possible with BMS
• 24 V system voltage

MPPT charge controller: maximum power yield guaranteed
With the help of Maximum Power Point Tracking (MPPT) technology, you can charge your battery even faster and make the best possible use of the solar system. Several times per second, the intelligent controller algorithm determines the point of maximum power output, which constantly fluctuates due to external conditions of temperature and solar radiation. Compared to simpler series controllers, a 10%-30% higher charging current can be generated. The integrated charging curve ensures, with the help of a four-stage IUoUo charging characteristic, that the batteries are charged at all times with an optimal voltage and suitable current. The parameters of the charging curve can be flexibly adjusted, making it possible to charge lithium-ion batteries in addition to lead batteries.

Reliable battery charger
Charge your battery gently and reliably with the help of the integrated battery charger. An external 230 V AC system can be used as an energy source. The integrated automatic charging system always charges with optimal current and voltage values depending on the state of charge of the batteries, ensured by a reliable charging curve. The charging current of 30 A ensures that the batteries are quickly recharged. Particularly noteworthy is the possibility of charging not only lead accumulators but also the new lithium-ion batteries.

Pure sine wave voltage for high demands
The TwinPeak converts the 24 V DC voltage of the battery into a clean, quartz-accurate sine wave voltage of 230 V and 50 Hz. This means that household appliances can also be operated on the go. With an output power of 3.0 kW, many powerful consumers such as espresso machines, chargers, household appliances such as blenders or immersion blenders, refrigerators or computers can be operated comfortably. Inductive loads such as stereo systems or televisions can also be reliably connected. A peak current twice as high as the nominal current can be drawn for a short period (1s). This means that even the high starting current of some devices is not a problem. The integrated deep discharge protection monitors the state of charge of the battery and automatically switches off consumers if the battery capacity is running low and further energy consumption would damage the battery.

External 230 V connection
If the energy from the solar system is not sufficient, the batteries can also be charged via the external connection. Simply feed shore power into your battery for this. Intelligent microprocessor electronics ensure that the batteries are always operated optimally. Overcharging is ruled out, and the batteries are constantly monitored.
With the integrated transfer switch (switching time 10 ms), uninterrupted operation of the consumers is easily possible. Input voltage and frequency range can be flexibly selected, making worldwide operation possible.

Variety of setting options
The combined unit has a backlit LCD display. Here, status information of the solar off-grid system such as the current voltage of the batteries, the connected load, PV current and voltage, and much more, can be displayed at any time. Of course, it is also possible to read the charge level of the battery or to get an exact error message in the (unlikely) event of an error. The almost unlimited setting options are also practical: Almost all electrical parameters can be freely adjusted: A charging current limit or the voltages in the different charging phases can be set if required.

Comfortable all-rounder
The device has a temperature and load-controlled ventilation system, so the device generates little noise. Thanks to overtemperature, overload and short-circuit protection, the device can also be operated safely in the event of malfunctions. The combination of many functions in one device eliminates annoying cable clutter and minimizes installation effort. UPS operation for uninterruptible power supply (UPS) is also possible. The built-in potential-free contact enables automatic starting of a generator or can function as an alarm contact when the battery charge level is low.

Software

The enclosed CD-ROM contains software that allows you to read out the TwinPeak data. Please note: We cannot guarantee the compatibility of the software.

Important note on the TwinPeak's shutdown threshold voltage

After commissioning your TwinPeak inverter, it is absolutely essential to correctly set the shutdown threshold voltage (also known as "low DC cut off voltage") in the menu for the battery type used. Only then will reliable and safe operation be ensured.

How to find the right value:

Please refer to the enclosed data sheet for the appropriate shutdown voltage. It specifies the recommended limit value that must be adhered to. The correct setting is crucial for efficient and long-lasting use of your system.
