| variant_note | LB0 drops the 'KTL' token: the model is 'SUN2000-5K-LB0', not 'SUN2000-5KTL-LB0'. It is the current single-phase counterpart to the older -L1 family at the same power points, but is materially different: 50 V startup vs 100 V, 40-560 V MPPT window vs 90-560 V, 16 A/MPPT vs 12.5 A, 20 A Isc vs 18 A, IP66 vs IP65, 425 x 376.5 x 150 mm vs 365 x 375 x 156 mm, battery max operating current 16.5 A vs 15 A and max charge power 6000 W vs 5000 W. It also has no 2 kW model and backup is via SmartGuard-63A-S0 only (the L1's Backup Box-B0 is not listed). Do not substitute for an -L1. |
