How many Pylontech US5000 batteries do I need for Stage 6 load-shedding?

For Stage 6 (4.5 hours per slot), most 3-bedroom homes need at least 2 × US5000 (9.6 kWh total). A 3-bedroom home typically uses 1–1.5 kWh/hour for essential loads. Two batteries give you 6–9 hours of essential backup.

Is the Pylontech US5000 compatible with Sunsynk inverters?

Yes. The Pylontech US5000 is natively compatible with all Sunsynk hybrid inverters (3.6 kW, 5 kW, 8 kW, 12 kW, 16 kW). Use the Pylontech-branded CAN/RS485 communication cable. Set the battery type to 'Pylontech' in the inverter settings.

What is the lifespan of the Pylontech US5000?

The US5000 is rated for 6,000 cycles at 90% depth of discharge, with 80% capacity retention. At one cycle per day, that is over 16 years. Pylontech backs this with a 10-year warranty.

How long does the Pylontech US5000 last during load-shedding?

Backup hours based on 4.3 kWh usable capacity at typical South African home load profiles.

Small home (1–2 bed)

3–4 hrs

Essential lights, Wi-Fi, TV, device charging. ~0.5–0.8 kW load.

Medium home (3 bed)

2–3 hrs

Above + fridge + 1 × air con. ~1.0–1.5 kW load.

Large home (4–5 bed)

1.5–2 hrs

Above + security + full kitchen. ~1.5–2.5 kW load.

Stage 6 load-shedding = 4.5 hours per slot. Stage 4 = 2.5 hours per slot. Hours are approximate — actual backup time depends on your real load and battery state of charge when the outage starts.
