High Voltage Lithium (LFP) modules with 100% DODĥkWh capacity per module scalable up to 30kWh Since the modules are connected in parallel, Huawei claims this unique design can achieve up to 10% more usable energy and 100% depth of discharge (DOD). Each 5kWh LUNA2000 battery module contains an Energy Optimiser, which optimises the charge and discharge of each module independently. In the field of energy storage, Huawei has accumulated more than ten years of R&D experience, so it is not surprising that the LUNA battery system is packed with many advanced features, including module-level optimisation. Huawei has spent a lot of time developing an AI-powered AFCI detection system which has so far proven to be one of the most reliable and effective systems currently available. With the increased focus on safety, especially in the US solar market with the strict regulations, the new Huawei optimisers offer advanced arc fault detection (ACFI) and rapid shut down in the event of damage or a fault in the solar array. Huawei use the ‘Powerline’ style communication system which transmits data via the DC cables connected to the panels.

This means very short strings of 4 panels can be used with full optimisation, something I’m interested in as it gives impressive flexibility in designing systems with shading issues. The SUN2000-450W-P optimisers feature a max input power rating of 450W, a max input current of 13A, and a wide voltage range from 8V to 80V. The new inverters are compatible with the next-gen, more powerful optimisers from Huawei. Remote troubleshooting via the monitoring portalĪdded safety - Zero string voltage when the inverter is switched off Monitoring at the individual panel, string and inverter level.
#Huawei smart controller install#
Maximise roof space – shading in winter less of an issueĬan install parallel strings of unequal lengths PID – Potential voltage and current leakage issuesĭifferent panels on one string – ideal for upgrading old systems Soiling – Dust, snow, bird droppings or birds
Temperature difference – thermal mismatch at different times of the day Panel damage – micro cracking, hot spots or water ingress Panel mismatch – manufacturing tolerances Shading – Trees, buildings, poles, wires, antennas, or rooftop structures Below are some common solar performance problems optimisers help overcome in addition to fault detection and panel level monitoring. Much like micro inverters, optimisers offer a wide range of benefits over standard string inverters. Optimisers, technically known as MLPE (module level power optimisation), have been available for many years from manufacturers like SolarEdge and Tigo energy, however, the Huawei smart PV optimisers ability to be partially deployed on only the panels which suffer shading is something that previously only Tigo optimisers offered. The first generation Huawei inverters required the add-on unit called the smart PV safety box, but fortunately, this odd-looking device is no longer required. Optimisers can be used without any additional components. This is something no other inverter manufacture has managed to deliver and solar installers like more flexibility when installing systems so this gives Huawei a big advantage. Oversizing PV is also rated to a modest 1.33 inverter rating depending on panel configuration.Ī stand out feature of the SUN2000L1 inverter range is the ability to function as a standard stand-alone string inverter, with partial optimisers or with full panel optimisation. In comparison, the SUN2000L inverters allow very short strings of 4 panels along with the flexibility to function with or without optimisers (more about optimisers below). This is coincidentally the direct opposite problem facing the main competitor SolarEdge, where the optimised systems have several issues with shorter strings below 7 panels. Although it’s worth noting, with the LG battery connected the upper voltage limit is reduced to 495V which limits string lengths to 11-12 panels.
#Huawei smart controller series#
Like the first generation inverter, the new FusionSolar SUN2000-L1 series is a hybrid or battery ready inverter compatible with the popular LG Chem battery and the new LUNA2000 Huawei battery system described in detail below. The new SUN2000-L1 series ranges from 2kW to 6kW and features ‘dual MPPT’s’ with a wide operating voltage range of 120V to 600V. The second-generation residential solar inverter was released in April 2020, only 2 years after the first version.
