Dyness Memory

Dyness memory with zero tax rate and fast shipping

A Dyness storage system from us is delivered completely VAT-free because photovoltaic components in Germany are subject to a zero VAT rate. That's around 19% less on your bill , no application or proof required. The Junior Box with 1,6 kWh costs €699, and the DL5.0C with 5,0 kWh costs €999.

Both models are part of our range of energy storage systems and usually leave our warehouse in Elze on the day of order. Shipping costs €6,95; we offer free shipping on orders over €100 . Customers in the Hildesheim area can also pick up their Dyness battery storage system directly from our collection point on Rex-Brauns-Straße.

If your energy consumption doesn't match the solar curve, a Dyness solar storage system pays for itself particularly quickly. The system runs at full capacity at midday, and in the evening, the electricity is supplied by the utility company. The battery bridges this gap , regardless of whether it's a balcony solar system or a rooftop installation. Both models use LiFePO4 cells, which are designed for several thousand charge cycles and are cobalt-free.

The Junior Box as a power storage unit for your balcony power plant

Anyone searching for a Dyness balcony power plant storage system almost always ends up looking at the Junior Box. This device operates AC-coupled, meaning it sits between the microinverter and the grid connection and requires no modifications to the DC side of your modules. Its 1,6 kWh output covers the power needs of a refrigerator, router, and other devices in standby mode for an entire night.

You can install it yourself without a professional. Simply connect the box between the inverter and the grid connection socket, pair it via the app, and then monitor in real time how much solar power is currently being fed into the cell. A standard-compliant grid connection, such as via a Wieland socket, is required. No meter replacement is necessary. Registration in the market master data register is the same as for a standard balcony power plant.

You can find supplementary materials in our "Balcony Power Plant Storage" category , from mounting brackets to monitoring systems. If your consumption increases or you add a second pair of modules, a Dyness energy storage system can be expanded later . This keeps the initial setup affordable without committing you to a specific technical setup. Renters also appreciate that the unit can easily be moved when they relocate, as no permanent wiring is required.

Significantly more self-consumption from the same solar system

A balcony solar power system without a battery typically covers 30 to 40% of its output within the household's own network, with the remainder fed into the public grid without compensation. With a 1,6 kWh buffer, this percentage increases to 60 to 70%, based on experience. At an 800-watt feed-in capacity, this translates to several hundred kilowatt-hours per year that you no longer need to purchase electricity. Compare this to your own nighttime consumption.

Larger households opt for the DL5.0C. Two stacked modules create a 10 kW Dyness storage system, which can also buffer heat pumps, hot water preparation, or charging in the evening. Suitable systems can be found in our PV system with storage category . As a rule of thumb, approximately 1 kWh of storage is recommended for every 1.000 kWh of annual consumption; anything above that only delays the amortization period.

Large rooftop systems with a suitable hybrid inverter operate with a Dyness high-voltage storage system. In our product range, this role is fulfilled by the Pylontech Force H3 with 10,24 kWh, while the Dyness models cover the AC and 48V ranges. This is precisely the more practical option for balcony power plants and retrofits in existing buildings.

Check the Dyness memory compatibility list before purchasing.

Checking the manufacturer's Dyness storage compatibility list should be done before placing any order. It shows which battery model communicates with which inverter via CAN or RS485. For AC-coupled devices, the question is quickly answered because the device is located after the inverter and only sees alternating current.

With 48V modules, the protocol determines whether they operate correctly or result in an error message. Therefore, check the battery voltage, communication interface, and firmware version of your inverter before ordering. The overview will help you match both models to the appropriate system type.

The correct product configuration usually makes the decision clear. If you have a balcony solar system, the Junior Box is the right choice; if you're planning a rooftop system with storage, you'll first need the appropriate hybrid inverter . The Dyness battery storage system follows as the second step. If you're planning a new system anyway, choose a hybrid-compatible device from the start. The battery connection will then be available from the outset. Alternatively, existing systems can be retrofitted on the AC side, which minimizes the modification and leaves the inverter untouched.

Electrical engineers will review your storage plan before you order.

PVundSO is run by Dirk Garve and Michael Westphal, both electrical engineers with extensive experience in building automation and photovoltaics. Your storage plan will therefore be reviewed by someone who has actually installed the equipment themselves , not a call center with a script. Send us your setup, and we'll tell you if the combination is viable.

Honest reviews of Dyness storage systems are important to us. 1,6 kWh is not a substitute for emergency power for the entire house, and a battery pays for itself more slowly than an additional module. However, those who want to permanently increase their self-consumption will get daily returns from the storage system that they would otherwise be wasting.

Over 2.900 reviews with an average rating of 4,97 out of 5 stars demonstrate that our support doesn't end after your purchase. If you'd like to discuss your Dyness storage system with us beforehand, you can reach us by phone, email, or WhatsApp. We'll gladly handle special requests. Unsure about the system configuration? Our PV system checklist will help you organize the key data before we discuss storage size and inverter options together.
