Detailed Feature Comparisons
Design and Construction: The Delta Pro has a rugged build with built-in wheels and handles, making it portable despite its large battery size. The Delta Pro 3 retains the same form factor but has a slightly refined design with a clearer interface and improved display. Both are well-suited for home and outdoor environments.
Battery Capacity: The Delta Pro includes a 3.6kWh base battery that can be expanded with additional units up to 25kWh. The Delta Pro 3 increases the base capacity to 4kWh and allows scaling up to 48kWh, making it more capable for whole-home backup during extended outages.
Output Power: The Delta Pro delivers 3600W of continuous output, enough to run large appliances. The Delta Pro 3 steps up to 4000W continuous power, giving users more headroom for energy-hungry equipment like HVAC systems or multiple kitchen appliances simultaneously.
Charging Speed: One of the most noticeable upgrades is charging speed. The Delta Pro takes about 1.8 hours to charge fully from AC. The Delta Pro 3 cuts that nearly in half, reaching full charge in roughly an hour, which is valuable in emergencies or off-grid scenarios.
Solar Charging: Both models support solar charging, but the Delta Pro 3 allows up to 2000W of solar input compared to 1600W on the Delta Pro. This improvement makes solar charging more efficient and reduces downtime between uses for those relying on renewable energy.
Display and Interface: The Delta Pro has a standard LCD showing battery percentage, input/output power, and runtime. The Delta Pro 3 offers a larger, higher-resolution display with a more intuitive interface, making it easier to monitor power usage at a glance.
Connectivity and Smart Features: Both models support Wi-Fi and Bluetooth through the EcoFlow app, but the Delta Pro 3 adds more seamless smart home integration. This means you can control power distribution and monitor energy consumption in real time from your phone or even integrate it with home automation systems.
Durability and Lifecycle: The Delta Pro already offers an excellent 3500+ charge cycles before dropping to 80% capacity. The Delta Pro 3 improves slightly with 4000+ cycles, providing a longer service life for heavy users.
