Components of the Huawei 4000W 20000Whdia Self-consumption Kit

9 x 455W JA Solar Mono PERC Solar Panel: guaranteed for 25 years and made of monocrystalline silicon from the famous international brand JA Solar. It offers one of the best products for our photovoltaic systems, as it is one of the best-performing monocrystalline models with excellent value for money. It can supply the solar system with about 1,350 Wh per day in winter and almost twice as much in summer. PERC technology with high performance monocrystalline half cells offers more than 20% efficiency for the size of the module. It measures 2112 x 1052 x 35mm and includes a junction box for each positive and negative cable with MC4 connectors at each end. The solar module includes an attached aluminum frame that allows it to be attached to any structure, allowing for additional dimensions.

1 x Falcat Universal Union Kit up to 45mm: contains all the necessary elements to connect the solar panels when creating a solar system with structures. This kit is specially designed to join two Falcat structures prepared for panels with a profile thickness of up to 45mm.

1 x Structure 5 Panels 30-45mm Coplanar Falcat: support to allow the placement of 5 solar panels on the roof with the correct slope and orientation. The panels are placed perpendicular to the structure and have the same slope as the surface on which they are installed. In this case, the structure is designed for panels of any length and has a universal press that accepts panel profiles from 30 to 45 mm. This is the most suitable type of construction for metal roofs, sandwich panels or concrete slab roofs. The product is supplied in a single package and can be connected to multiple structures of the same type using the appropriate connection kit.

1 x Structure 4 Panels 30-45mm Coplanar Falcat: support to allow the placement of 4 solar panels on the roof with the correct slope and orientation. The panels are placed perpendicular to the structure and have the same slope as the surface on which they are installed. In this case, the structure is designed for panels of any length and has a universal press that accepts panel profiles from 30 to 45 mm. This is the most suitable type of construction for metal roofs, sandwich panels or concrete slab roofs. The product is supplied in a single package and can be connected to multiple structures of the same type using the appropriate connection kit.

1 x Huawei Luna2000 5kWh Lithium Battery Module: a high-voltage energy storage module with a 10-year warranty and compatible with Huawei KTL-L1 and three-phase KTL-M1 single-phase inverters. A BMS is required on top for a complete system to exist and can be expanded with up to two units. 20, 25 or 30 kWh require an additional BMS module and a total of 4.5 or 6 battery modules. It has IP65 protection and has a total expanded capacity of up to 30 kWh for self-consumption systems using Huawei hybrid inverters.

1 x Huawei Luna2000 Lithium Battery BMS: a controller that acts as an interface between the inverter and the Huawei Luna battery. Compatible with Huawei KTL Single-Phase L1 Inverter and KTL Three-Phase M1 Inverter. This BMS sits on top of the battery and is used for systems from 5 to 15 kWh, depending on whether one to three battery modules are installed. 20, 25 or 30 kWh require additional BMS modules and a total of 4.5 or 6 battery modules. It has IP65 protection and an extended capacity of up to 30kWh for our self-consumption systems with Huawei hybrid inverters.

1 x Carlo Gavazzi EM112DIN Wattmeter: a device tuned to measure the amount of energy flowing through your home, optimizing the energy delivery of your inverter to the maximum to avoid feeding the grid or increase production according to your preferences You can control or in a self-consumption configuration. A very popular Carlo Gavazzi model that is widely compatible with many inverters on the market.

1 x Huawei SUN2000-4KTL-L1 4000W inverter: It has an output power of 4000W and is ready to use in grid connection installations. Lithium batteries can be added to store additional power for consumption during times of higher consumption than solar power and at night. It includes high-level features such as two MPPT trackers with very wide working ranges. It also includes support for a custom optimizer that prevents partial shadows, but it's perfect for being able to set two directions on the panel. Includes wireless communication, IP65 protection, 5-year manufacturer's warranty and more.

1 x Roll Unifilar Cable 6mm2 H1Z2Z2-K 20m red: special for electrical installations. Halogen-free flexible power cables for the most demanding industrial requirements.

1 x Roll Unifilar Cable 6mm2 H1Z2Z2-K 20m black: special for electrical installations. Halogen-free flexible power cables for the most demanding industrial requirements.

2 x WEIDMULLER PVStick Connectors - Most recommended if you don't have crimping tools that can connect normal MC4 connectors. They are compatible with all connector models that come standard with solar panels and require no tools to connect to the cable.
