Reference Design for 1200V Isolated I2C High Side Current Sensing for Solar Combiner Boxes
Description
This reference design is an isolated high-side current sensing design for a smart combiner box in a grounded or ungrounded system. The current sensing topology enables multichannel: sub ±1% error: isolated current sensing for high-voltage systems up to 1200-VDC: limited by the DC/DC transformer.
Features
- Isolated high-side current sensing of multiple photovoltaic stringsCapable of monitoring current within 1% full scale accuracySupport 1200V isolated current sensing via I2C in smart combiner boxesOption to connect additional INA260 devices to I2C bus
Applications
- String inverter
- Smart combiner box
- Expansion module
