I plan to buy two different types of Solax hybrid inverters, both of which are connected with Solax batteries, can I install them in my house at the same time?

If there is no communication between the two hybrid systems and both inverters are connected to batteries, when one of the batteries will be charged and discharged, the other storage inverter may recognise it as a load. It is possible to use one energy storage inverter as a grid-connected one. We recommend you do not connect batteries to the two hybrid inverters at the same time, only connect batteries to one of the two hybrid inivertes.
