Product description

This balcony power station set includes a micro inverter HMS-800W-2T with WiFi, two Trinasolar solar panels Vertex S+ TSM-NEG9R.28, each with 440 watts and a black frame, a Zendure AIO 2400 power station (1,200 watts, 2,400 Wh) and a 10 meter long adapter cable (AC trunk / BC05-BR3M-02 socket to protective contact) for direct connection to the domestic socket. Mounting material is not included.

The single-phase micro inverter HMS-800W-2T from Hoymiles converts the energy of the solar modules into usable electricity. Specially developed for mini PV systems such as balcony power plants, the inverter has an integrated industrial-grade WiFi module. With the user-friendly HMS Plug & Play cable, the HMS-800W-2T can be easily installed and connected directly to the socket. It offers real-time access to PV data via the smartphone and enables remote monitoring of the PV system via the S-Miles Cloud. The Hoymiles inverters are characterized by easy installation, high quality and low failure rates. The HMS-800W-2T with a nominal output power of 800 VA and two independent MPPT and monitoring functions can connect two solar modules.

The TSM-NEG9R.28 solar module from the Vertex S+ series offers excellent efficiency and aesthetics with 440 watts of power. The series is specially designed for rooftop applications and offers high mechanical strength, fire resistance and reliability even under difficult environmental conditions. The multi-busbar technology ensures better absorption, lower series resistance and high reliability. Thanks to the optimal size and low weight, easy installation and cost-effective transport are guaranteed.

The Zendure AIO 2400 is a 2.4 kWh all-in-one storage solution for balcony power stations that can be installed in just a few minutes. It contains a deep-cycle LiFePO4 battery, the Smart PV hub and the mounting space for a micro inverter, all in one compact housing. Thanks to the advanced self-heating technology, the AIO 2400 works perfectly even in frost. Integration into an existing balcony power station is easy and space-saving, with no messy cables. The dual MPPT maximizes efficiency by controlling the power point of two solar systems independently. With the Intelligent Flow Control, excess energy is stored efficiently. The system supports up to 1,200 W PV input and offers an adjustable power of 0-1,200 W for micro inverters. The IP65 water and dust resistance also allows outdoor installation. Thanks to universal MC4 cable connectors, the AIO 2400 is compatible with all solar modules and most micro inverters and can be easily set up, dismantled or relocated if necessary. In addition, the system operates almost silently with a noise level of 0 dB.

The advantages at a glance

  • Plug & Play installation
  • Produce your own green electricity
  • Payback in 4-6 years
  • Significantly cheaper than large solar systems
  • Reduces your electricity costs

Let the sun work for you - in 4 easy steps:

Step 1: Order

Order the balcony power plant from us in the Ostrom Store and it will be with you in 2-5 days.

If you are unsure, please contact us in our chat (the blue circle bottom right).

Step 2: Install

The ease of installation is one of the main advantages of balcony power plants. You can do it completely yourself and the included instructions show you step by step what you have to do.

For particularly easy installation, take a look at the set from WeDoSolar. Here you can find the WDS 640 Watt.

Step 3: Sign up

You must register your balcony power plant with the Federal Network Agency's market data register. In view of the Federal Government's new Solar Pact 1, the registration process has been greatly simplified and now only takes a few minutes.

Since April 26, 2024: Registration with your local network operator is NO LONGER necessary.

To register with the Market Data Register:

Step 4: Sit back and benefit

Congratulations, you did it! From now on you will produce green electricity and reduce your electricity costs at the same time. You can track production live via the app (manufacturer or Ostrom app*) and see at any time how much electricity your balcony power plant is producing.

Here are a few facts about how cool it is that you now own a balcony power plant:

Fact 1: A 400-watt balcony power plant replaces the electricity generation of approximately 400 kg of brown coal per year.

Fact 2: The production of your balcony power plant does produce CO2, but after just 1-2 years the CO2 emissions are offset by the green electricity generation of the balcony power plant and you produce 100% climate-neutral electricity.

Fact 3: In 3-5 years (or sooner if you receive a subsidy) your investment will have paid for itself and you will now receive free solar power.

*Currently only the balcony power plant sets from priwatt can be integrated into the Ostrom app.

Finally! Solar Package 1 is here.

No more registration with the network operator necessary

💪 You can now feed in 800 watts

Simplified registration in the market data register

🔢 Reverse-rotating meters (so-called bidirectional meters) are temporarily permitted

🔌 Schuko plug officially permitted
