\n \n✅ Why It Stands Out in South Africa
\n-
\n
-
\n
Reliable backup: In off-grid mode, switchover occurs in under 10 ms—ensuring a seamless UPS-like experience during power outages.
\n
\n -
\n
Efficient and compact: High DC/AC ratio (up to 1.3) allows installation of additional PV capacity without oversizing the inverter.
\n
\n -
\n
User-verified robustness: Solar professionals report robust long-term performance, often comparing favorably vs Victron or Huawei in reliability and price.
