Sunsynk ECCO 7kW is model SYNK-7K-SG05LP1, a single-phase hybrid inverter for low-voltage batteries. It fills the current ECCO range between the 5 and 8 kW models.
PV and battery interfaces
Maximum PV input is 10 kW, with two MPPTs and provision for two strings on each tracker. The MPPT range is 150 to 425 V and the maximum PV input voltage is 500 V. Array design must keep both operating current and cold-weather open-circuit voltage within the per-input limits.
The low-voltage battery input spans 40 to 60 V, with published maximum charge and discharge current of 175 A. A battery also needs supported battery-management-system communication and firmware compatibility. The current rating should not be applied to a battery whose own limit is lower.
AC and backup operation
Rated AC and UPS power is 7 kW. Maximum AC power is 7.7 kW, the ten-second off-grid peak is twice rated power and continuous AC pass-through is 50 A. Each describes a different operating boundary and should remain separately labelled in a system design.
Siting and identification
Current weight records conflict between 23.6 kg net and 24.9 kg. The nameplate and unit-specific installation document therefore control handling and mounting. Both records agree on IP65 protection and natural fanless cooling.
The exact-model sheet states a five-year warranty, or ten years with a Sunsynk battery. That does not align cleanly with the current range-page headline or formal warranty structure, so the dated terms supplied for the installation need checking.
