Scenario Overview
Wide-temperature, large-capacity cells for household storage, PV pairing and emergency backup, combining long warranty periods with the safety expectations in a home.
What separates home storage from commercial systems is that the installation environment cannot be controlled: a balcony, a garage, a basement, with temperatures swinging from 45℃ in midsummer to tens of degrees below zero in winter — and the user is not a trained technician. The RockSolid·Craft series retains 90% discharge capacity at -40℃, and the safety characteristics of its semi-solid electrolyte keep unattended household installations stable over the long term.
Configuration guidance covers pairing with rooftop PV and EV chargers, helping system makers build a complete residential product line.
Core Capabilities
02
Safety design for domestic use
The semi-solid electrolyte lowers leakage and thermal propagation risk, suiting unattended long-term operation.
03
PV pairing configuration
Battery sizing is recommended against rooftop PV capacity and household load curves.
Application Scenarios
Rooftop PV self-consumption
Storing surplus by day and discharging at night raises the self-consumption ratio.
Outage backup power
When the grid drops, essential lighting, refrigeration and communications keep running.
Customer Value
Longer warranty period
Longer cycle life supports a longer warranty commitment and a stronger end product.
Stable winter capacity
Low cold-weather fade keeps the user experience in northern markets close to nameplate.
Lower after-sales cost
Maintenance-free operation cuts the number of on-site service visits.
FAQ
Does 90% at -40℃ refer to discharge capacity or charging?
It refers to discharge capacity retention. Low-temperature charging still follows the BMS temperature window, and the strategy is supplied with the solution.
Can the packs work with our existing inverter brands?
This must be confirmed protocol by protocol. Send the target inverter models and we will assess integration and commissioning effort.
