Massive Capacity & Output: The DELTA Pro Ultra Inverter with 3 batteries offers roughly 18 kWh of usable power and a continuous output around 6.9 kW—enough for whole‑home backup or large appliances.
Expandable & Flexible: Supports additional batteries and multiple inverters for up to ~30 kWh or more, ideal for future upgrades or off-grid setups.
Advanced Solar & AC Input: Handles high-voltage solar input and standard AC charging, enabling hybrid solar/grid setups and fast recharge times.
Durable & Outdoor-Ready: LFP batteries, IP54-rated ports, quiet operation, and wide temperature tolerance make it suitable for utility or garage installation.
Smart Monitoring & Control: WiFi/Bluetooth connectivity with LCD display and app support allows real-time monitoring of usage, battery status, and system health.
Installation Considerations: Each battery weighs ~50 kg, inverter ~32 kg—requires sturdy support; professional installation is strongly recommended due to high power outputs.
Q1: What is the EFDPUPCS‑3‑BP bundle?
A1: It’s a system bundle including one DELTA Pro Ultra inverter combined with three 6 kWh batteries, giving a total base storage of around 18 kWh and an AC output capability of ~7.2 kW for whole‑home backup.
Q2: What output power and capacity does this system offer?
A2: With three batteries this setup offers about 18 kWh of usable energy and up to 7.2 kW continuous AC output from the inverter. It also supports expansion to much higher capacity and output when additional units are included.
Q3: What types of inputs and charging does it support?
A3: Supports AC charging, solar input (both high‑PV and low‑PV ranges), and grid/generator input. It allows large solar input and rapid replenishment.
Q4: What battery chemistry and lifecycle can I expect?
A4: The batteries use LiFePO₄ (lithium iron phosphate) chemistry and are rated for around 3,500 cycles to 80% capacity, offering long‑term durability.
Q5: Is this system expandable?
A5: Yes — the system is designed to scale. You can connect more batteries (and even multiple inverters) to increase total capacity and output to meet larger home or off‑grid demands.
Q6: What are the environmental and operational conditions?
A6: The unit operates in temperature ranges from about –20 °C to +45 °C (–4 °F to 113 °F) for charging/discharging. It features an IP54 rating (dust and splash resistant, when ports are covered).
Q7: What applications is this bundle ideal for?
A7: Ideal for home backup during outages, off‑grid living, large appliance support (including HVAC, EV charging), and as a solar + battery energy storage system for energy independence.
Charge regularly and avoid letting batteries fully discharge to maximize lifespan.
Keep the inverter and batteries in a cool, dry, and well-ventilated area.
Wipe surfaces with a soft, dry cloth; avoid harsh chemicals or water exposure.
Inspect connectors, ports, and cables periodically for dust or damage.
For long-term storage, keep batteries partially charged (50–70%) and check monthly.
