All-in-One Inverters – One System for Solar Energy and Storage

All-in-One inverters take solar systems to a new level by managing energy generation, energy storage, and grid interaction in a single system logic. In this category, you will find solutions designed for those who think long-term and want to manage their energy in a transparent, easily expandable system rather than in separate devices.

What does All-in-One inverter mean?

An All-in-One inverter not only converts the direct current produced by solar panels into alternating current, but is also designed to manage battery energy storage. Solar power generation, battery charging and discharging, grid feed-in or consumption, and backup operation in the event of a power failure all work together in a single system. This approach results in simpler installation, more transparent operation, and easier expandability later on.

Not a single product, but a complete system

It is important to note that All-in-One inverters are not to be understood as standalone products, but as parts of an interconnected system. In addition to the inverter, a compatible high-voltage battery module and the associated BMS unit are also required for energy storage to function. The inverter is the central element of the system, the battery provides the storage capacity, and the BMS ensures safe operation and control. Together, they form the energy storage system, which is why it is always advisable to choose All-in-One solutions as a system.

Battery energy storage and expandability

All-in-One inverters allow energy generated during the day but not used immediately to be stored and then returned to consumers later, typically in the evening or during peak consumption hours. Thanks to its modular battery design, the system can be adapted to initial requirements and gradually expanded later. This can be particularly advantageous if an electric car, heat pump or other major consumer is added to the system in the future.

Smart meter – optional but useful accessory

All-in-One systems can be optionally supplemented with a three-phase CT smart meter, which provides an accurate picture of consumption and network energy flow. This is particularly advantageous if the aim is to optimize self-consumption, limit exports, or monitor the operation of the system in more detail. The smart meter is not a prerequisite for the inverter to function, but it is a highly recommended accessory for many installations.

Who is the All-in-One inverter category ideal for?

This category is a good choice for those who are considering energy storage, want to reduce grid consumption, want to supply protected consumers even in the event of a power outage, and are looking for a unified system that can be expanded in the long term. All-in-One inverters are well suited for modern residential and small business projects.

SOLARKIT expert opinion

Based on SOLARKIT's experience, one of the biggest advantages of All-in-One inverters is their transparent system logic and future-proof design. The inverter, battery, and BMS together form the basis of energy storage, while the smart meter can be a useful addition for more accurate control and measurement. This approach ensures fewer compromises, clearer design, and long-term stable operation for both installers and users.
