Frequently Asked Questions
What can a 35 kWh Hope battery power?
A 35 kWh Hope system stores energy from your solar array for evening use and backup. The right size depends on your daily consumption — 35 kWh typically covers a meaningful share of a household's overnight and outage needs. Ask us for a tailored sizing based on your bill.
Can I expand the 35 kWh system later?
Yes. The Hope 5.0L-B1 is modular and scales in parallel up to 48 packs, so you can add modules to your 7-module (35 kWh) system as your consumption grows.
Is the Hope battery suitable for off-grid use?
Yes. The Hope 5.0L-B1 is a low-voltage battery designed for off-grid and backup inverters (SPF / SPE class), with CAN/RS485 communication for inverter integration.
