Deye SUN-MPPT-L01-EU-AM8 MPPT Module (200 kWp)

MPPT means maximum power point tracking: the electronics permanently adjust the way the panels are loaded, in order to draw as much power as possible from them in any weather. This module connects the panel field directly to the batteries of an industrial storage system, on direct current, without passing through alternating current any more. By bypassing a conversion stage, part of the losses disappear, so the energy produced reaches the batteries more completely.

The module takes up to 200 kW of panels, split over 8 independent trackers with 2 strings each, that is 16 inputs in total. Independent means that a group of panels which is shaded or oriented differently does not drag down the rest of the installation, which matters on complicated roofs with several slopes. The tracking efficiency exceeds 99.9%, and the conversion efficiency 99%, so the equipment's own losses remain small. It is an outdoor cabinet with IP65 protection, of 543 x 700 x 197.8 mm and about 48 kg, which works between -25 and +60 °C, with power reduction above 45 °C; a shaded and well-ventilated location helps to keep the power on very hot days.

Maximum photovoltaic power 200 kW, 8 independent MPPT trackers, 16 string inputs (2 per MPPT), MPPT voltage range 180-850 V with full-load operation between 450 and 850 V, maximum open-circuit voltage 1000 V, maximum input current 40 A per tracker. MPPT tracking efficiency above 99.9%, overall conversion efficiency above 99%. IP65 outdoor cabinet, 543 x 700 x 197.8 mm, approx. 48 kg, operating range -25...+60 °C with derating above 45 °C. Declared conformity: LVD 2014/35/UE, EMC 2014/30/UE, RoHS 2011/65/UE; it integrates with the PCS conversion module and with the high-voltage batteries of the Deye C&I platform, for systems from 125 kW up to 2.5 MW.

Who it suits

Suitable for an industrial project with a photovoltaic generator of up to 200 kWp feeding a Deye C&I storage system, especially when the roof has several orientations or shaded areas.

Terms explained

• String: A row of panels connected one after the other and wired to the same input of the equipment; this module accepts 16 such rows.
• Independent MPPT tracker: Each group of panels is optimised separately, so shade or a different orientation on one part of the roof does not lower the output of the other groups.
• Derating: The automatic reduction of power above a certain temperature, to protect the equipment; here it starts above 45 °C.

Technical specifications

Recommended applications

Technical details

Specifications confirmed from the manufacturer's datasheet

SUN-MPPT-L01-EU-AM8 is the maximum power point tracking module of the Deye commercial and industrial storage solution. It is used together with the PCS conversion module and with the high-voltage batteries, its role being to couple the photovoltaic generator directly to the DC bus of the storage system, without passing through the alternating current side. This architecture reduces the conversion losses when charging the batteries from the photovoltaic output.

The maximum photovoltaic power accepted is 200 kW, distributed over 8 independent MPPT trackers with 2 strings each, so 16 string inputs in total. The MPPT voltage range is 180-850 V, with full-load operation between 450 and 850 V, and the maximum open-circuit voltage allowed on the photovoltaic side is 1000 V. The maximum input current is 40 A on each tracker. The MPPT tracking efficiency exceeds 99.9%, and the overall conversion efficiency is above 99%.

The enclosure is an outdoor cabinet with an IP65 protection rating, with dimensions of 543 x 700 x 197.8 mm and a weight of approximately 48 kg. The operating range is -25...+60 °C, with power reduction above 45 °C. The product is declared compliant with the European directives LVD 2014/35/UE, EMC 2014/30/UE and RoHS 2011/65/UE and is part of the Deye C&I platform for systems from 125 kW up to 2.5 MW.
