95% Reduction in Power Outage Impact, 60% Savings on Electricity Bills
JOHANNESBURG, South Africa – March 1, 2023 – Faced with South Africa’s worsening load‑shedding crisis, a homeowner in Johannesburg has successfully reduced power outage disruptions by 95% and cut electricity bills by 60% after installing the WOWTIGER APOLO 12kWh APOLO 12kWhall‑in‑one solar‑storage system, achieving reliable and self‑sufficient home power.
In 2023, South Africa endured more than 270 days of load‑shedding. Johannesburg, one of the hardest‑hit cities, has long suffered from frequent blackouts, with rolling power cuts continuing almost uninterrupted throughout the year. In response, more and more South African households are turning to “PV + storage” solutions.
For this project, the homeowner chose the WOWTIGER APOLO 12kWh home solar‑storage system. Featuring advanced solid‑state battery technology, the APOLO series is available in three capacity options: 6kWh, 12kWh and 18kWh. The LFP solid‑state battery offers superior thermal stability, lower fire risk and longer cycle life compared to conventional liquid‑based lithium batteries.
In terms of performance, the APOLO system achieves up to 99.5% efficiency in utility mode and over 94.5% in inverter mode. It supports up to 5500W of PV input, with a maximum PV open‑circuit voltage of 500V and an MPPT operating voltage range of 120‑430V. The transfer time between utility and battery mode is just 10ms, comparable to professional UPS systems, ensuring seamless power transition during outages. The system is also equipped with comprehensive protections including over‑voltage, under‑voltage, overload, short‑circuit and over‑temperature protection, ensuring full safety.
After installation, the results have been remarkable: the owner experienced a 95% reduction in outage impact, with daily electricity use almost unaffected by load‑shedding; and electricity costs fell by 60%, demonstrating immediate economic benefits from the combination of solar generation and storage.
