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:
Hybrid Inverters
Hybrid inverters combine solar and battery management in a single unit. They handle both the conversion of solar energy and the charging/discharging of batteries, making them ideal for systems focused on self-consumption and energy independence.
• All-in-one solution for solar + storage
• Perfect for new installations
• Enables smart energy management and backup power
String Inverters
String inverters are the most common type used in traditional solar setups. They connect multiple panels in a “string” and convert the combined DC output into AC.
• High efficiency and cost-effective
• Best suited for unshaded, uniform panel layouts
• Centralized monitoring and maintenance
Power Optimizers
Power optimizers work alongside string inverters to enhance performance at the module level. They adjust each panel’s output to maximize energy harvest, especially in partially shaded or complex roof conditions.
• Panel-level optimization and monitoring
• Ideal for roofs with varying orientations or shading
• Improves overall system efficiency
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, Ethernet, RS485, Power Line Communication (PLC), cellular (4G)? Is it compatible with Smart Meter Gateways?

Standards & Future Readiness
Regulatory requirements for inverters continue to rise. Key aspects include:
• Standard: Inverters must be declared compliant with AS/NZS 4777.2:2020, which is the Australian and New Zealand standard for grid-connected inverters.
• CEC Approval: Inverters must be listed on the Clean Energy Council's (CEC) list of approved inverters.
• Region Settings: Inverters must be configured to the correct region settings, such as "Australia Region A" or "Australia Region B" depending on the specific requirements of the local network.
• Firmware Updates: Inverter firmware should be updated to the latest version compliant with AS/NZS 4777.2:2020. 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.

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.
• CEC Approval: Inverters must be listed on the Clean Energy Council's (CEC) list of approved inverters.
• Region Settings: Inverters must be configured to the correct region settings, such as "Australia Region A" or "Australia Region B" depending on the specific requirements of the local network.
