Frequently Asked Questions

How far can I expand the eBoost system?+
The eBoost scales from a single 16 kWh unit all the way up to 256 kWh by stacking multiple units together. This makes it suitable for everything from basic home backup to large residential or small commercial energy storage.
What is the advantage of integrated eWay cable management?+
The eBoost's integrated eWay system keeps all AC and DC cabling organized within a dedicated pathway. This results in cleaner installations, easier maintenance, faster inspections, and a more professional finished look.
How does the eBoost compare to the eVault MAX?+
The eBoost offers 16 kWh per unit with higher expandability (up to 256 kWh) and integrated eWay cable management. The eVault MAX provides 18.5 kWh per unit with a built-in BMS. Choose the eBoost for maximum scalability or the eVault MAX for higher per-unit capacity.
Is the eBoost suitable for off-grid living?+
Yes. With expansion up to 256 kWh and LFP chemistry for long cycle life, the eBoost is an excellent choice for off-grid homes that need multi-day energy reserves and reliable long-term storage.
