Note: Grid-tie only - the M5 has no battery port at all, unlike the M1 and MAP0. Four string inputs across two MPPTs, 30 A per tracker on two strings or 20 A on one, 40 A short-circuit. Watch the full-load MPPT window: 370-800 V, not the headline 200-1000 V. Below 370 V the inverter still runs but cannot reach rated output, which on a Pakistani winter morning is the difference between a string that works and one that clips. Maximum apparent power 13200 VA. Peak efficiency 98.4%, European 97.9%. Rated output current 17.3 A at 400 V. Smart air cooling, so it has a fan - not silent like the MAP0. 21 kg, IP66, 4000 m with derating above 2000 m. AFCI arc-fault protection built in. PV ceiling rises to 40,000 Wp with SUN2000-450W-P optimisers fitted throughout.
