Entry into modular home backup with a system that can be built up over time

Web Consensus Insights

The original DELTA Pro remains a common starting point for home backup, with coverage praising its modular batteries and 240V capability when paired. It is slower to recharge and less efficient than the newer Pro 3 and Ultra.

Top Pros

• Well proven, widely documented platform
• Expands to about 25kWh with extra batteries
• Pairs with the Smart Home Panel for circuit-level backup

Top Cons

• Needs two units and a hub for 240V
• Aging cells deliver less usable capacity per kWh

Web Consensus Insights

Reviewers describe the Apex 300 as BLUETTI best modular platform yet, crediting its 3,840W inverter, roughly 20W idle draw and a quiet, compact footprint. The battery inside the main unit is smaller than rivals at the same money.

Top Pros

• 3,840W inverter with 120V and 240V output
• Roughly 20W idle draw suits long standby periods
• Expands to about 58kWh in a compact footprint
