Essential accessories for your inverter
Inverter accessories ensure safety, control, and performance in self-consumption and off-grid installations. From meters for zero feed-in to communication modules and wireboxes, choosing the right accessory makes the difference during commissioning and daily operation.
What you will find in this collection
- Meters and CT clamps: necessary for feed-in limitation, bidirectional reading, and power balancing.
- Communication modules: Wi-Fi/LAN/4G, RS485/CAN for integration with BMS of lithium batteries and monitoring via portal/app.
- Wirebox/covers: management of inputs/outputs, protections, and professional finish of the equipment.
- Probes and sensors: temperature, irradiance, or generator start accessories (dry contact).
- Parallel kits and phase distribution (depending on manufacturer/model).
- Specific accessories by brand/series: dongles, gateways, antennas, upgrade kits.
Compatibility: the critical point
Before purchasing, check the exact compatibility of the accessory with your inverter (brand, series, and firmware). For hybrids, also confirm compatibility with the battery (lists of BMS supported by the manufacturer) to ensure correct SOC readings and charge/discharge limits.
Installation best practices
- Place the meter/CT where it actually measures the total flow (before branch circuits) and orient the clamp in the correct direction.
- For RS485/CAN communications, observe polarity, terminations, and use shielded cabling if recommended.
- Update the firmware of the inverter/dongle to the stable version compatible with your accessory.
- Configure zero feed-in and verify in monitoring that the reading matches the meter.
Recommended protections and accessories
- SPD DC/AC and disconnectors suitable for the inverter's range.
- Fuses in PV strings (if applicable) and in the battery for off-grid/hybrid systems.
- Battery monitors (shunt) for banks without BMS communication.
Summary
With the right inverter accessories you will achieve an installation that is safer, more reliable, and easier to manage. Choose certified meters/CTs, communication modules, and wireboxes for your model and complete the setup with suitable electrical protections for a trouble-free commissioning.
