Huawei is an inverter brand from China .Huawei has launced this model SUN2000-4KTL-L1 of series SUN2000-L1 which is Hybrid type meaning that it can can connect to both solar panels and energy storage and supply solar energy to the residential households including EV and Heat Pump.
Huawei the SUN2000-4KTL-L1 model of series SUN2000-L1 has 2 MPPT ( Maximum point tracking ) input for solar panel arrays , which can face 2 directions of your rooftop. If planned solar panels on your rooftop faces multiple directions then then home owner should purchase a multiple MPPT inverter. PathtoGreenHomes has identified compatible model as your installer will be unaware of incompatible of inverters with many latest solar panel models leading to sub performance of your PV System .

This 4kW model can be overloaded to 4.4 kW for always seconds which is useful to avoid inverter tripping (shutting off) loads like aircon , motor etc. which create surge power on the solar inverter for the first few seconds. Select the following models of inverter for best compatibility to all your home appliances especially in first few seconds
By 2025 thousands of residential inverters like you will be able to together create a stable national grid. This will result in additional income for the home owner. This series SUN2000-L1 of Huawei cannot connect to a mesh of distributed grid and perform advanced Grid-Support Grid forming Functions as a Distributed Energy Resource (DER) which is becoming common in developed countriesSuch smart inverters sense the grid (i.e. voltage and frequency) and can respond individually in ways that help maintain grid stability rather than just shutting off like tradional solar inverters. Select the best [Grid forming residential VPP inverters] (https://www.pathtogreenhomes.com/blog/what-is-vpp-and-solar-inverters/).
A non Smart solar inverter treats all household loads including Electric vehicle equally. A real time capability of solar inverter to deliver available/ maximum power to the electric vehicle is called PV Optimised. This model cannot charge an Electric Vehicle (EV) in a PV optimised or forecast based manner, in situations when solar power should feed the car and not the household loads. Select in [pathtogreenhomes.com] (pathtogreenhomes.com). The best EV charging solar inverter with PV optimization capability.
A non smart solar inverter treats all household loads including Heat pump equally. The real time capability of the solar inverter is to put an insulated heat pump as the last priority, only with excess solar power for space heating or space cooling .The priority of smart inverters shoud be as follows 1st EV, 2nd household loads , 3rd battery charging and lastly heat pumps. . This Huawei model cannot communicate with a smart grid ready Heat Pump. Select in [pathtogreenhomes.com] (pathtogreenhomes.com) the best Heat pump- compatible solar inverter
The standard warranty of this model SUN2000-L1is 10 years.Extended warranty may be seperately purchased. PathtoGreenhomes recommends solar inverter to have 12 years+ warranty to at least match product warranty of solar panels
