Huawei SUN2000-5KTL-L1 inverter 5kW single-phase

The inverter makes the link between the panels and the electrical installation of the house: it converts the direct current produced on the roof into the ordinary current from the sockets. This model is factory-prepared for storage, so if today you install only the panels, you can later add a Huawei LUNA2000 battery directly to it, without any other equipment between the two. The two independent panel inputs allow them to be mounted on two different slopes, each group working at its own pace.

The 5.000 W rated power and the up to 7.500 Wp of accepted panels suit a house with a single-phase connection and ordinary consumption. On the battery side it can charge and discharge 5.000 W, that is it can support the household loads in the evening, not just a few sockets. It weighs 12 kg and measures 365x375x156 mm including the bracket, so it fits easily even on a narrow wall, and the IP65 enclosure allows outdoor installation. Its own night-time consumption is below 2,5 W, that is practically invisible on the bill, and production and the status of the installation are tracked from the FusionSolar app, through the integrated WLAN module.

PV input maximum 600 V, two independent MPPTs, working range 90-560 V, 12,5 A maximum current per MPPT, Isc 18 A, maximum recommended PV power 7.500 Wp. Single-phase output 220/230/240 V, 5.000 W rated, 5.500 VA maximum apparent power, 25 A maximum current. Battery port 350-560 V, 5.000 W on charging and 5.000 W on discharging, compatible with the LUNA2000-5/10/15-S0 and LUNA2000-7/14/21-S1 modules. Maximum efficiency 98,4% and European weighted 97,8%, IP65, 365x375x156 mm, 12 kg, range -25...+60 C, night-time consumption below 2,5 W, RS485 communication and integrated WLAN; compliant with EN/IEC 62109-1/-2, EN 50549-1 and G98/G99.

Who it suits

Suitable for a house with a single-phase connection and an installation of up to 7,5 kWp, which wants to start without a battery, but keep the option of adding one later.

Terms explained

• Wp (watt-peak): The power a panel delivers under standard test conditions; 7.500 Wp means the sum of the powers of all the installed panels.
• MPPT: The circuit that continuously seeks the point at which a group of panels delivers the most power; two MPPTs mean two independent groups.
• IP65: The protection code of the enclosure: completely protected against dust and resistant to water jets, so it can be installed outdoors.

Technical specifications

Recommended applications

• Single-phase homes with high self-consumption
• Systems prepared for storage with LUNA2000 batteries
• Outdoor installation in tight spaces (12 kg, IP65)
• Monitoring and maintenance through FusionSolar

Technical details

Specifications confirmed from the manufacturer's datasheet

Huawei SUN2000-5KTL-L1 is a 5 kW single-phase inverter from the residential L1 series, prepared for storage through the direct connection of Huawei LUNA2000 batteries. The photovoltaic input accepts a maximum of 600 V, with two independent MPPT trackers, MPPT working range 90-560 V, 12,5 A maximum current per MPPT and 18 A short-circuit current. The maximum recommended photovoltaic power is 7500 Wp.

On the AC side it delivers 5000 W rated power, 5500 VA maximum apparent power and 25 A maximum current, at 220/230/240 V single-phase. The battery port works between 350 and 560 V, with 5000 W maximum charging power and 5000 W discharging, being compatible with the LUNA2000-5/10/15-S0 and LUNA2000-7/14/21-S1 modules.

The maximum efficiency is 98,4%, and the European weighted one 97,8%. The IP65 enclosure allows outdoor installation, the dimensions with bracket are 365x375x156 mm, the weight 12 kg, and the operating range -25...+60 C. Night-time consumption is below 2,5 W. Communication is via RS485 and the integrated WLAN module, with monitoring in the FusionSolar app. The product complies with EN/IEC 62109-1/-2, EN 50549-1 and G98/G99, alongside the other grid connection standards in the manufacturer's documentation.
