Explanation per series
L1 series: Single-phase hybrid inverters (2KTL – 6KTL). Being phased out. Supports up to 11A string input, less suitable for modern solar panels.
LB0 series: Successor to L1. Hybrid with 16A input — perfect for high-power solar panels.
M1 series: Compact three-phase hybrid inverters up to 10KTL. Compatible with battery storage, optimizers and grid relief.
MAP0 series: Three-phase hybrid series with asymmetric load — ideal for residential three-phase applications.
MB0 series: For larger hybrid systems up to 25KTL, with dual battery inputs.
M3 series: String inverters (30–50KTL) for commercial applications. No hybrid option, but robust and efficient.
MC0 series: String inverters (30–50KTL) for commercial applications. Successor to the M3 series with increased current inputs for the latest panels.
M2/MG0: Utility-grade inverters up to 150KTL. Suitable for solar parks and large commercial systems. MG0 supports 21A input current.
