Safety Guide
1. The 5-year payment installment service is provided by CityPay. 2. For 30 minutes of use. 3. The 3-ton central air conditioner's LRA rating must be within 120A. 4. X-Fusion technology ensures that all AC output sockets provide optimal output in terms of wattage and amp. In fast charging mode, the output will always be 7.2kW, no matter how much the input is.Switch to fast charging for a continuous 7200W output. 5. If you connect the DELTA Pro Ultra to PV system circuits installed on or in buildings, according to NEC regulations, the system shall include a rapid shutdown function to ensure operation safety and reduce shock hazards for emergency responders. If you wish to connect the DELTA Pro Ultra to PV system circuits, a pre-purchase consultation must be completed by a qualified electrician or installer. 6. If three or more battery packs are stacked, an EcoFlow Fixing Metal Tab is needed to hold them in position. EcoFlow Portable Stand allows you to stack one DELTA Pro Ultra Inverter and 5 Batteries. However, for long-time use, do not move the whole set of products if you connect the inverter to three or more batteries and lock casters by flicking the brake down, so that the product can't be moved anymore. 7-10. At an output voltage of 120V, the maximum power output DPU can achieve is 3600W. At an output voltage of 240V, the maximum power output can increase up to 7200W.
