Atom N Series 1 to 4 kW On Grid Inverters
The Uno Atom N Series is designed for small grid-connected PV systems that use a single principal roof orientation or string group. Ten power ratings from 1 kW to 4 kW allow close matching to modest residential and small-business loads. A low 80 V start-up, 70-500 V MPPT range, zero-export capability, compact natural-cooled housing and optional remote connectivity support efficient, practical installations where space and simplicity matter.
