How does the Sunsynk MAX 16kW compare to the ECCO range?
The MAX 16kW is significantly larger than the ECCO 3.6 kW and 5 kW models. It has 3 MPPT trackers (vs 2), 6 DC inputs (vs 2), 32 kW surge (vs 7.9–11 kW), and supports up to 15-unit three-phase parallel operation (vs 16-unit single-phase only on the ECCO). The MAX is designed for large domestic and small commercial installations.
Which BMS cable do I need?
For Pylontech, REVOV, and Hubble Lithium batteries: use SUN-CAN-3M. For Freedom Won batteries: use F-WON-CAN-SUN.
Can I install the MAX 16kW in a three-phase configuration?
Yes. Up to 15 units can be connected in a three-phase configuration (5 per phase) for a maximum output of 240 kW.
What fuse size is recommended?
Size 3 fuse holder with appropriately rated size 3 fuses is recommended due to the high battery DC currents. Maximum passthrough current is 150 A with a recommended circuit breaker size of 100 A.
