Usage notes and compatibility The battery model is suited to mobile cleaning, remote sites, and locations where cable dragging is impractical. The power converter model includes a 110V/220V to 24V DC supply and a long power cord of more than ten meters. It is better suited to fixed or nearby gridconnected installations; dragging the power cable can limit mobility and may not be ideal for very largearea power stations. Telescopic rod lengths and materials support roof access from ground level within the specified reach for each model. Select rod length based on installation height and accessibility. Typical applications Residential rooftop solar arrays: remove bird droppings and dust buildup without climbing onto the roof. Commercial or small utility installations: regular onsite cleaning with the power converter model for panels near an outlet. Remote or offgrid systems: batterypowered kit allows cleaning of groundmounted arrays or remote installations without mains power. Technical reminders Choose the battery kit for mobility and convenience. Choose the power converter kit for continuous power access and longer operation time without recharging. Verify the telescopic rod length and model to ensure adequate reach for your panel layout. Included accessories such as replacement bristles, water pipe, and connection joints allow straightforward assembly and maintenance.
