SUN5000-150K-MG0 + MERC-1100/1300W-P 150 kW inverter with module-level optimizers
Country: China · Model: SUN5000-150K-MG0 + MERC-1100/1300W-P
A set of the 150 kW SUN5000-150K-MG0 inverter and MERC module optimizers of 1100 or 1300 W. It suits rooftop solar plants with complex shading and higher fire safety requirements, where a conventional string layout loses generation.

Description
The inverter has a maximum power of 165 kVA, an efficiency of 98.6% and works with 380, 400 or 480 V networks. On the DC side there are 12 inputs at a maximum voltage of 1100 V. The MERC optimizer is installed under a module, accepts up to 125 V, has an efficiency of 99.5% and an IP68 enclosure, so it withstands water and dust on the roof. Module-level optimization raises energy yield by 5–30%, because shade from a parapet or a ventilation shaft reduces the output of only the shaded panels. During emergency shutdown each optimizer lowers its voltage to 1 V, and no dangerous string voltage remains on the roof. AFCI arc protection works together with rapid shutdown.
How to choose
The set is justified where some panels are shaded or where the fire service requires rapid shutdown at module level. The optimizer rating of 1100 or 1300 W is chosen to match the power of the modules it serves. On an open roof without shade it is simpler to use a string inverter without optimizers, for example the SUN2000-50KTL-M3 rated 50 kW.

FAQ
By how much do MERC optimizers increase solar plant yield?
The gain is 5–30% depending on shading and the non-uniformity of the module array.
What voltage remains on the roof after SUN5000 rapid shutdown?
Each MERC optimizer lowers its output voltage to 1 V, so the string becomes safe for maintenance and firefighters.
What is the input voltage of the MERC-1300W-P optimizer?
The optimizer accepts up to 125 V at the input, with an efficiency of 99.5% and IP68 ingress protection.
How many PV inputs does the SUN5000-150K-MG0 inverter have?
12 inputs at a maximum voltage of 1100 V, and a maximum output power of 165 kVA.
Is there arc protection in the SUN5000 set with MERC?
Yes, the inverter has AFCI, and the optimizers perform rapid shutdown of each module.
