This is the reply from Indra:
Good afternoon,
Regarding your question about running two Indra Smart Pro chargers on a single-phase supply: yes, this is possible with each charger using its own CT clamp on the same incoming meter tails for independent load curtailment.
On a single-phase installation:
- Each charger can independently monitor the total load on the supply using its own CT clamp and will adjust its charging rate as needed to protect the main fuse.
- Each CT clamp should be installed at the main supply, before any junctions, and as close to the main cut-out fuse as possible, with the arrows facing the grid (incoming supply).
With this setup, both chargers will independently perform load curtailment based on the total current measured by their own CT clamps, so there is no requirement for a dedicated multi-charger load-sharing configuration in this scenario.
If you have any more questions or would like help checking your planned setup details, just let us know and we can escalate this to a human agent for you.
Thank you for contacting Indra Renewable Technologies Ltd.
