How do prepaid STS tokens interact with home solar export in South Africa?

Answer first: Ask the metro whether your prepaid meter supports the SSEG programme you want, whether a swap to conventional/AMI is mandatory, and who pays — prepaid solar · prepaid→conventional · bi-directional · smart meter compatibility.

Planning tips

• Start the meter-change conversation at quote stage, not handover week.
• Budget appointment lag in the SSEG timeline — SSEG timeline.
• Keep token receipts while comparing pre/post solar spend — token tips · monthly savings.

TOU prepaid

Some prepaid TOU products still need careful reading before EV night charging assumptions — TOU prepaid EV · Cape Town TOU.

SA desk notes that keep quotes honest

Ask every partner for Incl. VAT line items, NRS-listed SKUs where relevant, and who owns metro paperwork after deposit. Compare at least two written scopes before you pay — read a quote · choose installer · NRS list · SSEG.

Worked homeowner checklist

1. Photograph the DB, roof and meter before the survey.
2. Export twelve months of kWh or summer+winter bills.
3. Write Stage priorities (fridge, routers, lights) before shopping kWh.
4. File CoC, warranties and SSEG refs in one folder after handover.

Tariff and fixed-charge reminder

Self-use savings sit on top of fixed charges that do not disappear. Model both before you celebrate a payback slide — fixed charges · monthly savings · export vs self-use · tariffs 2026.

Safety and paperwork close

• No DIY on dual-supply boards or MC4 strings.
• Keep dual-supply labels readable for inspectors.
• Register warranties before the deadline printed on the pack.

Monitoring and aftercare

Watch daily kWh, backup SoC before forecast Stages, and any new earth-leakage or isolation alarms. Export CSVs monthly so cloud portal changes do not erase your history — monitoring numbers · Wi-Fi dongle · SoC settings.

When to call vs when to wait

Call for burning smells, repeated RCD trips, zero production in full sun with isolators on, or firmware prompts you do not understand. Wait-and-log for single Stage-restore blips that do not repeat — fault codes · nuisance trips · MC4.

Season-test the system in the month that hurts

July nights and January heat expose weak designs. Schedule a deliberate outage test in winter and a temperature check in summer. Fix what those tests show while the installer still answers the phone under warranty.

Screenshots from a mild March afternoon are not a test.

Sources homeowners should open themselves

Open the live metro SSEG page, the OEM manual PDF for your exact inverter SKU, and the tariff code on your latest bill before you argue with a salesperson. Screenshots age; primary pages change. Cross-check any rand band on this desk against those primaries the week you buy — metro tariffs · tariffs 2026 · NRS list · SSEG · SSEG cost.

Stage-season operating rules

• Know which breakers are essentials before the app says Stage 4.
• Pre-charge only as far as your written SoC policy — not 100% forever.
• After restore, glance at earth-leakage and isolation alarms before heavy loads.
• Keep a paper copy of dual-supply labels and OEM contacts in the kitchen drawer.

Aftercare calendar

1. Month 1: confirm monitoring app + CSV export works.
2. Month 3: visual roof/MC4 glance from the ground after storms.
3. Month 6: reconcile bills vs production; check fixed charges.
4. Month 12: warranty registrations, cleaning, SoC policy review.

Bottom line for SA homeowners

Treat this as a decision aid with named trade-offs, not a brochure. Demand Incl. VAT scopes, NRS-listed hardware where it applies, written SSEG ownership, and a backup board that matches how your household actually survives Stage. If a partner cannot explain those four items without slogans, keep shopping — get quotes · check a quote · read a quote · is solar worth it · payback · monthly savings.

Keep primary PDFs (metro, OEM, warranty) beside this article. When figures disagree, the live primary wins. Update your own notes after tariff changes each year — tariffs 2026 · metro tariffs · VAT on solar · bond finance · lease vs buy · selling with solar.

Worked token diary

For 30 days before install, photograph each token purchase and weekly remaining units. After commissioning, continue the diary for 30 days. The delta is mostly self-use education — not proof of feed-in — token tips · monthly savings · bill still high · fixed charges.

Friendly credit and vendor quirks

Some prepaid UX features look like “solar credits.” Confirm with the metro helpdesk before you celebrate. Misread tokens create angry Facebook posts and wrong installer blame — smart meters · meter cost · prepaid change.

Local follow-ups worth booking

Put “meter SKU + swap lead time + who pays” on every competing quote — read a quote · SSEG cost · SSEG timeline · SSEG.

Desk close — what to do this week

Photograph your DB and roof, export twelve months of kWh (or summer plus winter bills), write Stage priorities on one page, and request two Incl. VAT quotes that name SKUs, export mode, meter plan and who lodges SSEG. File CoC, warranties and insurer acknowledgement in one folder after handover. That pack beats any brochure PDF — get quotes · check a quote · read a quote · SSEG · CoC · declare insurance · warranties · choose installer · red flags · is solar worth it · payback · monthly savings · metro tariffs · load shedding · fixed charges.

Vendor tip: keep one unused token as a float during the meter-swap week so the household is not dark if appointments slip — and photograph the old and new meter faces for the SSEG folder.

Homeowner checklist before you spend

• Write the decision on one page: what problem this solves under Stage, what it costs in rand bands, and who signs the CoC.
• Ask the installer for the primary PDF (OEM, metro tariff, SSEG form) that backs any number on the quote.
• Photograph serials, labels and the DB before and after work — claims and warranty desks start there.
• Keep guest monitoring logins with the invoice so a future buyer or insurer can verify the plant.

Stage-weekend reality check

Model the worst Stage window you actually live through, not a brochure day. Essentials first, then comfort loads. If the plant cannot cover fridge, lights, fibre and one work laptop through that window, resize before you chase export credits — essentials · Stage strategy · Stage 4 battery · SoC settings · Stage table.

Documents to keep for five years

Invoice PDF, CoC number, dual-supply photos, export-limit screenshot, CT polarity photo, firmware version, and the guest portal login. When a fault or sale appears later, that pack beats a WhatsApp thread — labels · export limit · CT clamps · firmware · selling with solar.

Quick questions

Will solar stop me needing tokens?

Self-use reduces imports; fixed charges and night loads still need a plan.

Can I export on prepaid immediately?

Often not — confirm meter rules for your metro first.

Who books the swap?

Usually metro/Eskom process via installer or account holder — get it in writing.
