Combined inverter WS-TwinPeak TP1k12 MPPT

WATTSTUNDE WS-TwinPeak 1000W Combi Sine Wave Inverter for Off-Grid Solar Systems

Become independent from 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 device:

1. Pure sine wave inverters for off-grid solar systems
2. Battery charger
3. Solar charge controller (MPPT)
4. Shore power connection

The TwinPeak is the ideal solution for realizing a fully functional off-grid solar system: By connecting PV modules (maximum 500 Wp), the connected battery can be charged anytime and anywhere.
In addition to reliably operating 12V DC devices, this powerful combination unit also allows you to connect 230V AC devices. It generates a pure sine wave voltage to power your devices at home.
The device is rounded out by a shore power connection: This allows energy to be fed into your self-sufficient system from an external source such as a grid connection. The TwinPeak is particularly suitable for small off-grid solar systems in remote cabins or small garden sheds that are intended to operate independently of the grid.

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

The following are the distinguishing features of the TwinPeak device :

• High-performance off-grid inverter: Sine wave inverter, solar charge controller, battery charger in one
• True sine wave voltage for 230 V appliances (max. 1000 W continuous power)
• Integrated high-performance 50A solar charge controller: Connect solar panels with up to 500Wp power
• Integrated 20 A 12 V battery charger for automatic battery charging
• Shore power connection: if required, power can be fed in from a grid (integrated transfer switch with 10 ms switching time)
• Numerous settings options: priorities, battery type, etc. Almost all parameters can be freely adjusted. See the manual for further information.
• LCD display: System information can be read quickly and easily (battery, PV system, and consumers)
• Suitable for AGM/Gel batteries (lead-acid batteries), LiFePO4 possible with BMS
• 12 V system voltage

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

Reliable battery charger
Charge your battery gently and reliably using the integrated battery charger. An external 230 V AC power supply can be used as the power source. The integrated automatic charging system always charges with optimal current and voltage values, depending on the battery's state of charge, ensured by a reliable charging curve. The 20 A charging current ensures that the batteries are quickly fully recharged. A particularly noteworthy feature is the ability to charge not only lead-acid batteries but also the new lithium-ion batteries. With the TwinPeak, you are therefore ideally equipped for the future.

Pure sine wave voltage for high demands
The TwinPeak converts the battery's 12V DC voltage into a clean, quartz-accurate 230V 50Hz sine wave. This allows you to power your home appliances while on the go. With an output power of 1000W, it can easily operate many small appliances such as coffee makers, chargers, small household appliances, or computers. Inductive loads like stereo systems or televisions can also be used reliably.
For a short period (5 seconds), a peak current twice the rated current can be drawn. This means that starting up some high-performance devices is no problem. The integrated deep discharge protection monitors the battery's charge level and automatically switches off the connected devices when the battery capacity is running low and further power consumption would damage the battery.

External 230 V connection
If the energy from the solar panels is insufficient, the batteries can alternatively be charged via the external connection. Simply feed shore power into your battery. Intelligent microprocessor electronics ensure that the batteries are always operated optimally. Overcharging is impossible, as the batteries are constantly monitored.
The integrated transfer switch (10 ms switching time) ensures uninterrupted operation of the connected devices. Input voltage and frequency range can be flexibly selected, enabling worldwide operation.

Numerous setting options
The combination device features a backlit LCD display. This allows you to view status information from your off-grid solar system at any time, such as the current battery voltage, connected load, PV current and voltage, and much more. Naturally, you can also check the battery charge level or, in the (unlikely) event of a malfunction, receive a detailed error message. The virtually unlimited configuration options are also very practical.
Almost all electrical parameters can be freely adjusted: Charging current limiting 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 makes very little noise.
Thanks to over-temperature, overload and short-circuit protection, the device can be operated safely even in the event of malfunctions.
By combining many functions in one device, annoying cable clutter is eliminated and installation effort is minimized.
The already low standby power consumption can be further minimized by activating energy-saving mode. UPS operation for uninterruptible power supply (UPS) is also possible.

Important note regarding the cutoff threshold voltage of the TwinPeak

After commissioning your Twinpeak inverter, it is essential to correctly set the cut-off voltage (also known as "low DC cut-off voltage") in the menu to match the battery type being used. This is the only way to guarantee reliable and safe operation.

Here's how to find the right value:

Please refer to the enclosed datasheet for the appropriate cutoff voltage. It specifies the recommended limit value, which must be strictly adhered to. The correct setting is crucial for the efficient and long-lasting operation of your system.
