Full Solis S6 Hybrid reviewSunsynk ECCO 5kW Hybrid
Unusual among the 5kW hybrids in that its maximum AC output (5,500W) is genuinely above its 5,000W rating rather than just a higher apparent-power figure. The 120A charge and discharge current and 35A maximum continuous AC passthrough make it the most off-grid-oriented unit in this list, and the datasheet names both G98 and G99 in its grid regulations. In practice it is a G99 job: rated output current is 22.7A, with 25A maximum. Maximum efficiency is 97.60%; the warranty is 5 years, and at 20.5kg it is among the lighter hybrids.
