- The RDSS smart-meter rollout is reaching solar homes across India.
- The core conflict: a new meter is swapped in without net mode enabled.
- Then export stops being credited, or a prepaid balance drops despite solar.
- The fix is the DISCOM's: enable net/bidirectional mode and re-link the sanction.
- Confirm the meter supports net mode — it varies by OEM and firmware; verify current.
The Revamped Distribution Sector Scheme (RDSS) is replacing old meters with smart and prepaid meters at scale, and those meters are now reaching homes that already have rooftop solar. When the swap happens without net metering set up correctly, export quietly stops being credited. This is a fast-growing operational problem, and almost no one connects the dots for EPCs. This guide does.
The RDSS smart-meter shift
RDSS is the central scheme driving DISCOMs to install smart prepaid meters across the country. The rollout target is very large and the installed count changes every quarter, so treat any specific figure as an estimate and verify the latest number with the Ministry of Power or your DISCOM. What matters for EPCs is simple: a solar customer's meter may be swapped at any time.
Net metering is run by each DISCOM and governed by each SERC, so how a smart or prepaid meter handles solar export differs by state, meter OEM and firmware. Confirm whether the specific meter on a solar site supports net mode before you rely on it.
Why smart and prepaid meters conflict with solar
The conflict is configuration, not the meter itself. A smart meter can do net metering, but only if it is set for bidirectional, net operation and that mode is enabled. Many are installed in a plain import-only mode by default, because the swap programme is about metering, not solar.
Prepaid logic makes it worse
A prepaid meter draws down a balance as the customer imports. If it is not netting solar export, the balance falls even while the panels are generating — so the customer pays for power their solar should have offset. That is the symptom that brings the angry call to your office.
Symptoms, causes and fixes
Match the symptom your customer reports to its cause and fix. Most are a configuration or record-linking gap the DISCOM can correct.

Prepaid meters and solar credit
A prepaid meter can work with rooftop solar, but only if it nets export against the balance. When it does, the solar generation reduces the rate at which the prepaid balance falls, and any surplus is credited per the state's settlement rule.
When it does not, the customer sees the balance drop in daylight and assumes the solar is broken. The system is usually fine — the meter is not netting. Some states have a trigger, often cited around a monthly-units threshold, for moving a consumer to prepaid, but that figure changes; verify the current trigger with your DISCOM. The read the net-metered bill guide helps a customer read a prepaid statement correctly.
Does the meter support net mode?
This is the question that decides everything. A meter supports net mode if it records both import and export and is configured for bidirectional operation — which depends on the make, model and firmware. Net-mode support varies by meter OEM and firmware, so you cannot assume it.
Confirm before go-live and after any swap
For a new install, confirm the DISCOM will provide a bidirectional-capable meter set for net mode. For an existing solar site, the moment a smart meter is swapped in, confirm net mode is enabled on the new meter. The bidirectional and solar check meters guide explains what the meter must record.
How to fix a smart-meter net-metering problem
When a swap breaks net metering, follow these steps. Speed matters — the longer it runs uncorrected, the more credit the customer loses.
Capture the closing reading before the swap
If you know a smart meter is coming, photograph the existing meter reading and any carried credit. This protects the customer if credit goes missing in the transition.
Confirm the new meter supports net mode
After the swap, check whether the new smart or prepaid meter is configured for bidirectional, net operation. Many are not enabled for solar by default; this is the most common cause.
Raise a written request to enable net mode
Ask the DISCOM in writing to enable net/bidirectional mode or load the correct firmware, quoting the net-metering sanction and the new meter serial. Keep the acknowledgement.
Re-link the sanction to the new meter
Make sure the net-metering sanction and any carry-forward credit are linked to the new meter serial on the DISCOM system, not the old one.
Verify on the first bill
Once corrected, check the first bill or prepaid statement shows export being netted. If it still looks wrong, escalate as a metering dispute.
If the bill or statement still shows export uncredited after the DISCOM corrects the meter, treat it as a metering dispute — see meter reading disputes for the escalation route.
Prevention checklist
You cannot stop the RDSS rollout, but you can protect every solar customer from losing credit when their meter is swapped.
- Net-mode confirmed — the meter records import and export, configured for net.
- Meter serial on file — recorded against the net-metering sanction.
- Closing reading captured — before any swap, with carried credit noted.
- Sanction re-linked — net-metering record points to the new meter serial.
- First statement checked — export is netted on the bill or prepaid balance.
- Customer briefed — they know to flag a meter swap to you straight away.
- State trigger verified — any prepaid-conversion threshold confirmed as current.
How SuryaHub helps you handle meter swaps
The RDSS rollout turns every past install into a future support ticket, unless you have the records to act fast. SuryaHub keeps the meter serial, the closing readings and the net-metering sanction on each job, so when a smart or prepaid meter is swapped in, your team can prove the credit and re-link the sanction without digging through old files. The service view turns the angry call into a quick, documented fix. SuryaHub is pre-revenue; real pilots are Suryantra Energy and RGESPL, and RDSS figures here are estimates that change, not guarantees.

Frequently asked questions
Why does a smart meter stop net metering from working?+
A smart meter stops net metering from working when the new meter is not configured for net or bidirectional mode after the swap, so it records import but does not credit solar export. The fix is to ask the DISCOM to enable net mode or load the correct firmware on the meter.
What is the RDSS smart-meter conflict with solar?+
The RDSS smart-meter conflict is when the Revamped Distribution Sector Scheme replaces a solar customer meter with a smart or prepaid meter that is not set up for net metering, so export stops being credited. EPCs must confirm the new meter supports bidirectional net mode and have the DISCOM enable it.
Do prepaid meters work with rooftop solar?+
Prepaid meters can work with rooftop solar only if the meter supports bidirectional net operation and the DISCOM enables it, so export is netted against the prepaid balance. Many prepaid meters are not enabled for solar by default. Verify the meter supports net mode before relying on it.
How do I know if a smart meter supports net mode?+
To know if a smart meter supports net mode, check whether it records both import and export and is configured for bidirectional operation, which depends on the meter make, model and firmware. Net-mode support varies by meter OEM and firmware, so confirm with the DISCOM for the specific meter before go-live.
What if solar credit is lost when a meter is changed?+
If solar credit is lost when a meter is changed, document the closing reading and any carried credit from the old meter, then ask the DISCOM in writing to transfer the credit and re-link the net-metering sanction to the new meter serial. Keep the acknowledgement in case it becomes a dispute.
How does SuryaHub help with smart-meter swaps?+
SuryaHub records the meter serial, the closing readings and the net-metering sanction on each job, so when a smart or prepaid meter is swapped in, your team can prove the credit and re-link the sanction fast. SuryaHub is pre-revenue; real pilots are Suryantra Energy and RGESPL.
