Hi Hec, Yes, you can connect 2 of the same units in series at most. Furthermore, please also note: 1. The slave unit must be fully charged before being connected. 2. Must not charge the main unit when the slave is connected. For a better experience and efficiency, it is highly recommended to use EcoFlow solar panels. If you want to choose solar panels from other brands, please make sure: 1. The specification of the solar panel meets the requirement of the device, for example, 8A Max,11-30V 110W for the RIVER 2; 2. The connector of the solar panel is MC4 type (so that it can be connected to the EcoFlow solar charging cable) or XT60 female type (so that it can be connected to the power station's input port directly). If its connector is of another type, you need to purchase an MC4 adapter or an XT60 adapter. 3. No controller comes with the solar panel. There is an MPPT board that controls solar charge inside the power station already. A separate controller would affect the solar charge. Note: EcoFlow does not provide free service for any damage to the product caused by improper operation of the third-party solar panels.
