S450S/S800S/S1000S/S1600S — microinverter, 450–1,600 W
Country: China · Model: S450S/S800S/S1000S/S1600S
The S450S, S800S, S1000S and S1600S microinverters deliver 450–1,600 W into a single-phase 220 V grid at up to 96.2% efficiency. They go into residential solar PV systems where the modules run at no more than 60 V DC.

Description
The line has four models that differ in output power, from 450 W on the S450S to 1,600 W on the S1600S. Each microinverter mounts on the racking next to the modules, so DC voltage on the roof stays at or below 60 V. There are no long high-voltage strings on the roof, and what runs down from each unit is already AC. Check the module datasheet so that its open-circuit voltage stays under 60 V even in frost. Several units share one AC line that ends on its own breaker in the house panel. Operation is monitored through iSolarCloud, which shows yield and status for every unit.
How to choose
Pick the model by the total power of the modules it will carry, keeping within the 60 V input limit. The S450S and S800S cover a small array of a couple of modules, while the S1000S and S1600S take more panels per unit and cut the number of mounting points. If you need a battery and backup during outages, look at the SH3.0–6.0RS hybrid inverter, 3,000–6,000 W with a high-voltage battery, or the SH3–10RL for a 48 V battery. For a three-phase commercial roof on a 400 V grid, the SG25/30/36/40CX-P2 string inverter at 25–40 kVA fits better.

FAQ
What input voltage do the S450S–S1600S microinverters accept?
Maximum PV voltage is 60 V. Choose modules whose open-circuit voltage, with a margin for cold weather, stays within that limit.
What is the efficiency of the S800S microinverter?
Maximum efficiency is 96.2%, and the maker gives the same figure for all four models.
What grid do the S-series microinverters connect to?
A single-phase 220 V grid, with the microinverter line brought into the panel through its own breaker.
How do I monitor S1600S microinverters?
Through the iSolarCloud service. It shows the yield of each unit, so a faulty one is found without walking the whole roof.
Why is a microinverter safer on a roof than a string inverter?
Roof DC stays at 60 V or less, while strings for the SG25/30/36/40CX-P2 string inverter can run at up to 1,100 V.
