About Inverters
The inverter is the heart of every photovoltaic system – both technically and strategically. It not only converts direct current (DC) into usable alternating current (AC), but also takes on a wide range of tasks that go far beyond basic energy conversion.
For installers and system planners, choosing the right inverter is therefore a complex decision with far-reaching consequences. As a PV wholesaler with international experience, Krannich Solar supports professionals in making precisely these decisions.
The Central Role of the Inverter
The inverter’s primary function is to convert DC from solar modules into AC for household or grid use – or vice versa. At the same time, it acts as a control center, a safety element, and a communication interface.
A high-performance inverter has a significant impact on energy yield, system stability, and long-term future readiness. No other component connects as many parts of a PV system – from the generator field to battery storage to energy management.
Types of Inverters
At Krannich Solar, we categorize inverters into four main groups:
- PV Inverters
Designed specifically for grid-tied PV systems without storage. They feature high efficiency, modern MPPT technology, and grid synchronization. Use case: classic feed-in systems. - Battery Inverters
AC-coupled inverters that allow battery storage to be added to existing PV systems. Especially relevant for retrofit projects or hybrid setups with multiple energy sources. - Hybrid Inverters
All-in-one units that manage both the PV array and the battery system. They enable efficient self-consumption optimization and are particularly attractive for new builds. - Microinverters
Compact inverters mounted directly on individual solar modules. Ideal for shaded roofs, east-west orientations, or small-scale systems like balcony setups. While installation effort is higher, individual module performance can be maximized.
Choosing the Right Inverter – Key Criteria
Selecting the right inverter depends on a number of technical and contextual factors, including:
- String Length, Input Voltage, MPPT Inputs:
Not every inverter handles arbitrary string lengths or asymmetric configurations. Strings must match the MPPT input specifications and voltage range.
- Battery Compatibility:
Inverter and battery must be compatible – which is not always the case. Our storage overview helps identify suitable combinations.
- Application & Grid Connection:
Must the inverter meet grid constraints (e.g., 70% feed-in rule)? What is the intended application? What other devices must it communicate with?
- Communication:
Via Wi-Fi, LAN, Modbus, RS485? Is it compatible with Smart Meter Gateways?
An experienced wholesale partner helps balance technical and economic considerations.
Standards & Future Readiness
Regulatory requirements for inverters continue to rise. Key aspects include:
- Compliance with standards such as DIN VDE 0126-1-1, VDE-AR-N 4105 or 4110
- Grid compatibility & feed-in management
- Expandability for dynamic electricity tariffs (e.g. Smart Meters, variable pricing)
- Load management (important for large systems or smart home integration)
A future-proof inverter should offer modern interfaces, automatic firmware updates, and grid-friendly functionality. This is becoming a decisive factor – especially for eligibility in subsidy schemes or energy trading.
Overview of Brands & Technologies
The inverter market is broad but far from uniform. Krannich Solar offers a curated portfolio of leading manufacturers with clear technological focus:
- Microinverters: APsystems, Enphase
- Battery Inverters: Kaco, SMA, SolarEdge
- PV and Hybrid Inverters: from a range of trusted brands [add list as required]

Brands include: ABB Stotz-Kontakt, Conduct, Eaton, IMT, LevelX Energy, Phoenix Contact, Santon, Solar-Log, Solar Manager.
Often Overlooked Aspects
Beyond performance and efficiency, there are additional factors that are not always evident in datasheets but can make a real difference for installers:
- Installation Effort:
Device weight, wiring complexity, required training or certification, manufacturer installation support, and on-site conditions. - Service Access & Remote Maintenance:
Can the inverter be serviced remotely? Many systems support monitoring via app or web interface. - Accessories & Expandability:
Energy meters, backup power functionality, UPS capability, and additional compatible components – all of these can influence system planning.
Choosing the right inverter involves multiple technical and economic considerations.
As an experienced PV wholesaler, Krannich Solar supports installers, planners, and specialist dealers with product selection, system planning, and logistical support – offering a clearly structured portfolio to meet every requirement.
