Reports honestly
Load, tamper events and reverse flow are logged at the meter, not inferred from the billing system afterwards.
Prepaid metering & energy sales
Sell the kilowatt-hour you just generated
A mini-grid without collection is a donation. ENA supplies prepaid meters for its own networks and for estates and captive sites, and runs the vending path behind them — register a device once, then sell units to it from the web or the app.
Top up a meter
Pricing is quoted live against the connection's own tariff before you pay. A backup token is issued with every purchase, and a meter that is offline simply queues the credit until it reconnects.

What the device does on its own
Queues purchases
An offline device holds credit for fourteen days and flushes the moment the link returns.
Auto top-up floor
Set a kWh floor and the wallet tops the meter up before it runs out, rather than after.
Sub-accounts
Estates and landlords split one supply into tenant accounts, each with its own balance and history.
Bulk registration
Register a whole network from a CSV in the console rather than one device at a time.
Operator reporting
Revenue reconciled against meter data, monthly and exportable.
Operating a network?
Bulk registration, tenant sub-accounts, the vending API and revenue reports all live in the operator console.
