Electronics & accessories for photovoltaics - inverters, charge controllers & more

Photovoltaic systems consist of components that efficiently convert solar energy into usable electricity. At Offgridtec, you’ll find high-quality electronics for solar Systems - tested, compatible, and at fair prices. Photovoltaic technology for every need.

Electronics for Your Photovoltaic System

Regardless of size or location, every PV system needs reliable electronics: charge controllers protect the battery, (module) inverters convert direct current to alternating current, and the right cables and connectors ensure secure connections.

Generator, inverter, Controller - how it all works together

The PV modules (generators) supply the energy. A voltage converter or inverter transforms this into usable 230-V electricity. The charge controller charges the PV storage system in a controlled manner. With properly coordinated cabling, protection, and monitoring technology, your system runs efficiently and safely - whether grid-connected or off-grid.

The Right Inverter for Your Energy System

The inverter is one of the most important components of any solar system. Different devices are used depending on the application. Grid-tied inverters are frequently used for traditional grid-connected systems. They convert the generated solar power and feed it into the home’s electrical system or the public grid.

If you also want to integrate a battery storage system, hybrid inverters offer a particularly flexible solution. They connect solar modules, battery storage, and loads into a single system and enable a higher level of self-consumption of the generated solar power.

Off-grid storage inverters are suitable for self-sufficient energy systems. These devices were developed specifically for stand-alone systems and ensure a reliable power supply even without a grid connection.

Module inverters are frequently used for balcony power plants and smaller PV systems. They are connected directly to the solar module and allow for particularly easy installation.

Battery chargers and charge controllers for a reliable power supply

A stable power supply doesn’t end at the solar panel. With the right battery charger, you can charge AGM, gel, or lithium batteries safely and gently. Modern chargers automatically monitor the state of charge and ensure optimal battery life.

Charging inverters play a particularly important role in RVs, campers, and boats. They efficiently utilize the energy from the alternator and reliably recharge the service battery while driving.

Photovoltaics for Hot Water and Electric Mobility

Solar power isn’t just for powering electrical appliances. With smart solutions like Fothermo’s water heaters, you can use excess solar energy directly to heat water. This increases your self-consumption and helps you use your PV system even more efficiently.

Electric mobility is also becoming increasingly important. The combination of a photovoltaic system, storage, and charging infrastructure makes it possible to charge electric vehicles with self-generated solar power.

Accessories and Peripheral Devices for Professional PV Systems

Only with the right peripherals can you create a reliable overall system. In the categories of peripherals, electronic accessories, and DIY electrical engineering, you’ll find components for installation, monitoring, control, and custom expansions of your solar system.

These include, among other things, displays, monitoring solutions, safety technology, communication modules, switches, and many other components for professional energy projects.

Fothermo develops innovative hot water solutions for photovoltaic applications. The systems use solar power directly to generate hot water and enable particularly efficient use of excess energy.

Solar Electronics - the Foundation of Every PV System

The electronics of a solar system include charge controllers (PWM/MPPT), inverters (stand-alone/hybrid/module), battery chargers,DC/AC protection technology (fuses, surge protection, load break switches), and monitoring systems.

An MPPT charge controller maximizes module output and protects the battery. The inverter converts the power to alternating current. Combined with the right cabling and monitoring, you get a stable, efficient system.

FAQ - Electronics in Photovoltaics

1. What electronics are needed for a PV system?
   Typically, these include solar modules (generator), an inverter, a charge controller, a storage system (optional), wiring, protection/distribution equipment, and monitoring.
2. Why do I need an MPPT charge controller?
   It optimizes the flow of energy from the module to the storage system, charges more efficiently, and protects against overcharging or deep discharge.
3. Can a system operate without an inverter?
   Only with pure DC loads. An inverter is required for household appliances or feeding power into the grid.
4. What is a hybrid inverter?
   A hybrid inverter combines solar modules, battery storage, and loads in a single device. This allows solar power to be used directly, stored, or fed into the grid.
5. When do I need a storage inverter?
   Storage inverters are primarily used in battery systems and off-grid installations. They ensure that stored energy is made available as usable AC power.
6. Which charge controller is better: PWM or MPPT?
   MPPT charge controllers operate much more efficiently and extract more energy from the solar panels. They are usually the better choice, especially for larger systems.
7. Which manufacturers are particularly popular in the solar electronics sector?
   Among the best-known brands are Victron Energy, Hoymiles, Growatt, Votronic, and Fothermo. They offer solutions for photovoltaics, energy storage, electric mobility, and mobile power supply.
8. What’s important when it comes to wiring and connectors?
   The correct wire gauge (e.g., 4/6/10 mm²), MC4 connectors compatible with the original equipment, proper crimping, strain relief, and adequate protection (fuses, surge protection).
9. How do I choose the electronics for my project?
   The application (home, RV, off-grid), module power, battery system (AGM/LFP), and desired functions (backup/hybrid) determine the selection. We’d be happy to advise you.
