What does the MC100L do within an Atmoce system?
The MC100L Lite is a compact central hub that safely connects and manages the interaction between solar microinverters, battery storage, the grid connection, and home loads for smaller single-phase installations.
How much solar and battery capacity can the MC100L support?
The MC100L supports up to 5kW of PV power on a single branch and up to 7kWh of connected battery capacity, suited to compact residential systems.
What is the difference between the MC100L and the full MC100?
The MC100L is a smaller, single-branch unit rated for up to 5kW PV and 7kWh battery capacity in a more compact enclosure, while the full MC100 supports up to 10kW PV across two branches and 21kWh of battery capacity.
Does the MC100L come with the gateway already fitted?
Yes. The unit ships pre-installed and pre-connected with the M-Gateway Lite board, along with its breakers and current transformer, for a streamlined installation.
Is the MC100L suitable for outdoor installation?
Yes. It carries an IP65 environmental rating with reinforced insulation, suitable for both indoor and outdoor mounting.
