Hybrid inverters: WKS Evo Circle vs WKS Evo MAX II

Choose the inverter that suits your needs:

The WKS Evo Circle PRO 6.5 kVA 48 V is the ideal technical solution for an autonomous or hybrid solar system. It combines power and intelligent energy management. It ensures a stable power supply thanks to its fast-switching UPS (backup) function (10 to 20 ms, depending on the mode). A key technical feature is its programmable dual AC output.		The WKS Evo MAX II 10 kVA 48 V is a high-performance, modular hybrid solar inverter designed for high-demand residential or semi-collective installations. It stands out for its high power, operational flexibility and intelligent interfaces.

Lithium batteries

Choose the battery that suits your needs:

The Pylontech US5000 TheLeaptonLiFePO4EL-A05 5.12kWh 100Ah •Pylontech US5000:the "market standard/ESS ecosystem" choice The US5000 is a widely used model in residential applications (rack/ESS format), with modularity of up to 16 units and CAN/RS485 communications for UPS integration. The page highlights its reliability, modularity and service life of up to 6,000 cycles at 80% DOD. •Leapton EL-A05:the choice for "harsh conditions/outdoor use" Its key differentiators are its IP65 rating and heating function, which allows it to remain operational (discharge) down to -20°C, which is very useful if the battery is installed in an unheated room, garage, technical shelter or outdoors. It also boasts a power rating of 1C (100 A) ≈ 5.12 kW, which is useful for power demands.
