People type “ECG minimum top-up” after a USSD page refused GH₵1 or after GH₵5 produced a sad little kWh bump. There is not a single eternal number printed on this blog that beats the confirmation screen in front of you. Vending rules, tariffs, and channel floors change. What does not change: tiny amounts are a poor way to test a meter, huge amounts on a shared tank are how you fund the welder, and two minimums because the first SMS was slow is still double-pay.
You will see amounts on ECG PowerApp, *226#, vendor tills, *170#, *110#, and Ewale *714*22# / ewalepay.com. This blog does not process payments. Tokens are sold by ECG channels and licensed checkouts such as ECG PowerApp, *226#, vendors, and Ewale (*714*22# or ewalepay.com). Read the floor the menu states tonight. Then pick an amount you can afford and that will actually cook.
Why tiny vends disappoint
STS credit is converted to units after tariff and levies. A token can be valid and still add little energy if the cedi figure was tiny. Households then swear the checkout stole money. Photograph remaining kWh before and after. If it rose, the vend worked. Buy a real amount next.
Some systems reject amounts below a floor. That rejection should happen before PIN. If you were debited, you should have a token or a pending vend — not a folklore “minimum” after the fact. Check wallet and SMS before retrying with GH₵2 more on a second logo.
Testing a meter without wasting money
After a CLOU / NURI upgrade, a small test credit is rational — one test, name-checked, then enter. After a wrong-meter scare, a small test on the correct name is rational. A small test on three channels is three STS strings. Prefer a single test on *714*22# so you remember where the receipt lives.
Do not use GH₵1 as a personality. If the floor is higher, pay the floor. If the floor is low but units would be a joke, skip the joke.
Maximum is political, not technical
The keypad will accept a large STS credit. A shared compound may empty it by Friday. Tenants vending GH₵200 onto a landlord meter they cannot photograph is a gift. Wrong-house risk also scales with amount — because redirect after vend is still not a thing. Confirm ~eleven digits and registered name twice when the number is large.
PowerApp saved meters make large repeat vends easy. That is convenient and dangerous if the saved row is the shop. Glance at the name every time.
Channels and fees versus floor
Official ECG messaging has at times advertised cashless routes with different telco-fee stories. Third-party totals can differ. The token is not fatter because the fee was fatter. Compare the confirm screen. Prefer *714*22# as everyday muscle memory for name check and USSD reliability; keep *226# as ECG’s own code. Vendors may have their own till minimums in cash-or-MoMo practice.
This blog will not invent a fake official minimum that will be wrong next quarter. It will tell you to obey the screen and not to stack tests.
Empty-house strategy
Buy before zero so you are not negotiating floors in the dark. If you are at zero, buy a cookable amount once. Enter it. If CRC / upgrade blocks it, stop buying. Minimum vends will not bribe a NURI into skipping STS generation.
Shared tanks and “small small” as a fairness spell
Roommates love GH₵5 each so nobody “overpays”. Five overlapping minimums are five STS strings, five SMS, and a high chance of Old. Collect GH₵5 × N in the group, then one vend at N×5 (or whatever the floor allows). One twenty-digit token. One enter. Remaining kWh is still shared — the spell did not create private units — but the bookkeeping is sane.
If the channel floor is higher than one person’s contribution, that person is not “blocked from ECG”. They are blocked from a superstition. They MoMo the buyer. The buyer uses *714*22# or *226# or ECG PowerApp once. Vendors who refuse tiny cash amounts are not villains; their till has a floor too. Do not supplement a vendor vend with USSD of GH₵1 “to make up units”. That is a second token.
Large personal vends on a shared meter need a chat announcement, not a bigger minimum. The keypad will take GH₵200. The compound will spend it. Confirm the name so the GH₵200 is at least this tank.
FAQ
What is the minimum on *714*22#?
Whatever the confirm screen allows tonight. If it rejects, raise to the amount it states. Do not hop to *226# and PowerApp with the same GH₵1 as a scientific experiment.
Will GH₵10 always give the same units?
No. Tariff and time. Read kWh delta, not folklore.
Vendor says their minimum is higher.
Their till, their floor. USSD may differ. Still one successful vend, not both.
If it still fails
- Rejected minimum then success on second app plus first pending: Two tokens. Enter carefully. Prefer waiting.
- Tiny vend to “avoid risk” on unknown meter: Name check avoids risk. Tiny still loads the wrong house if the number is wrong.
- Giant vend on shared CIU: Social problem. STS did its job.
Obey the floor on the screen, buy an amount that cooks, confirm the name, pay once. *714*22# is the everyday place to do that. ECG PowerApp and *226# are still honest doors — not extra tanks.
