Frequently asked

Does Sonar CMS work with non-Sonar chargers?

Yes. Any charger that speaks OCPP 1.6J or 2.0.1 can be onboarded onto the network.

What is the difference between Sonar CMS and Sonar Software?

Sonar Software is the owner-facing dashboard for your revenue and sessions. Sonar CMS is the operator-grade control layer that manages the chargers themselves — protocols, load, firmware and network health.

Can I run a private fleet depot on it?

Yes. Depot mode supports scheduled charging, pooled fleet billing and load balancing across the depot's sanctioned supply.

Do you support roaming with other networks?

Yes, roaming and aggregator integrations are supported so your stations appear in partner apps.
