The MARSTEK CT003 P1 Smart Meter is the perfect addition to your MARSTEK home battery system. By connecting directly to the P1 port of your smart electricity meter, the CT003 provides your battery with real-time information about your household's energy consumption and grid export. This enables the battery to automatically charge and discharge at the optimal moments, maximizing the use of your self-generated solar energy.
With the MARSTEK CT003, you increase self-consumption, reduce your dependence on the electricity grid, and lower your energy costs.
The MARSTEK CT003 continuously reads data from your smart electricity meter. Based on your household's real-time electricity consumption, the home battery automatically determines when energy should be stored and when stored energy should be supplied back to your home.
Instead of exporting excess solar power to the electricity grid, surplus energy is stored for later use. When your solar panels are not producing enough electricity, your home automatically uses the energy stored in the battery first.
The real-time communication between your smart meter and your MARSTEK home battery ensures that every kilowatt-hour of solar energy is used as efficiently as possible.
The battery automatically charges whenever excess solar power is available and discharges when your home requires electricity. This significantly increases self-consumption and helps reduce the impact of decreasing net metering or feed-in compensation schemes.
The free MARSTEK App gives you complete visibility into your energy system at all times.

This allows you to optimize your energy consumption and maximize the return on your solar investment.
The MARSTEK CT003 has been designed for quick and straightforward installation.
Simply connect the device to the P1 port of your smart electricity meter, pair it with your Wi-Fi network using the MARSTEK App, and your system is ready to operate.
No complicated configuration or electrician is required.
The CT003 supports both Wi-Fi and Bluetooth, ensuring a reliable connection throughout the installation process. Its external antenna provides excellent wireless performance, even when installed inside a meter cabinet.
Please note: The MARSTEK CT003 P1 Smart Meter is supplied without a USB power adapter. A standard 5V USB-A power adapter is required. In most cases, an existing USB charger from a smartphone, tablet, or other USB-powered device can be used. The required USB power cable is included.
By not including a power adapter, unnecessary electronic waste is reduced and existing USB chargers can be reused.
The MARSTEK CT003 has been specifically developed for MARSTEK energy storage systems and supports simultaneous communication with multiple compatible MARSTEK home batteries.
This makes the CT003 suitable for both existing installations and future battery system expansions.
