The LOGITEX system is an island-OFF-Grid system without registration.


With 1000Wp we heat up to 17,000 liters of water per year in Germany with a 1000W heating element

from 10 degrees to 55 degrees with a real production of approx. 900kWh.


(4-person household / 2000Wp / 2000W heating element / 34,000 liters per year / Approx. 1800kWh per year)

Water heating is subject to the laws of physics and mathematics,

including Ohm's law.

DC - Wattmeter / Switch

DC measurement in a photovoltaic system refers to the measurement of the direct current (DC) generated by the solar modules.
This type of measurement is critical for monitoring system performance, as it allows for accurate tracking of the amount of energy generated before it is converted to alternating current (AC) for household consumption. DC measurement can optimize system efficiency, identify potential problems early, and ensure the system is operating at peak performance. This is especially important for systems designed to directly utilize DC energy, such as water heating.

LX Trinkwassertank 

The stationary storage tanks with a capacity of 300-1000 liters, which use the electricity generated ecologically with the help of photovoltaic modules to heat drinking water.
Stationary hot water tank with a side flange and a heat exchanger, suitable for various heat sources, with the possibility of installing a radiator TT (electric radiator TPK or TJ 6/4").

LX DC - Heating element

The special thing about the Logitex heating elements is that they do not work with alternating current, but with direct current.

The basic version offers water heating (e.g. as a balcony power plant without registration) from 1000W and uses the sun all day long.

All combinations are possible upon request; upon request, we can build a wide range of variants and performance levels to ensure the PV system operates as efficiently as possible.

Dry ceramic heating elements, wet elements for stainless steel and enamel, versions also for transferring PV power in water - when the battery storage is full - to DC 48V

LX - Hybrid air conditioning

Since 2019, the LX has been a hybrid air conditioner that can both cool and heat, primarily using energy from photovoltaic panels. We offer the following models: LX35 and LX50.

It's an air conditioning system that's powered by the electricity generated by photovoltaic modules and can be controlled either via a remote control or via a smartphone app thanks to Wi-Fi. It's very efficient. It also ensures thermal protection and reliable control of the entire system.

LX - Hybrid AC/DC Wandwarmwasserbereiter

The LX ACDC/M (M K and KW) ABC water heaters represent a new technical solution for water heating using environmentally friendly energy sources.
Solar energy is used for hot water preparation, which uses photovoltaic modules to generate direct electrical current that heats the water in the tank.
A direct connection to the photovoltaic modules is an original solution that eliminates energy losses, making the system highly efficient. It also ensures thermal protection and reliable control of the entire system.

"We will create a suitable offer for your house"

Solutions also for houses with multiple apartments

System-Logitex also offers solutions for multi-unit buildings. Preheating or zero-cost solar heating is the optimal solution for reducing costs for each individual apartment or even the entire building in a shared hot water and circulation system.


The most commonly used solutions HERE


- Photovoltaics without bureaucracy and approval?

- Photovoltaics only for yourself without the consent of the energy distributor?

- Cool in summer, warm in winter - when the sun shines?

- Photovoltaics with 3x, 4x or 5x longer lifespan?

- Photovoltaics without expensive batteries?

- Photovoltaics with 2x, 3x or 4x faster repayment Your own deposit?

Did you know that...

That about 10kWh of energy is needed to heat the 160-liter water tank?
So much more energy can be stored than in an expensive battery storage system?
BUT - wHow much does a 160-liter tank cost and how much does a 10kWh battery cost?

A water tank and an air conditioner generate more than half of the electricity costs...
BUT IT CAN WORK FOR UP TO 9-10 MONTHS AT NO COST, ONLY WITH PHOTOVOLTAICS...
