HJ Series
Home Energy Storage
Reliable home battery backup for solar self-consumption and energy independence — UL/CE certified, factory-direct engineering. 15kWh to 20kWh LiFePO4 systems for single-family homes, villas and apartments.

LiFePO4 Home Battery Storage Built for Solar Self-Consumption & Backup Power
AURALIS home energy storage systems use lithium iron phosphate (LiFePO4) battery technology to safely store solar energy for later use, provide backup power during grid outages, and support peak-valley electricity price arbitrage. Compatible with mainstream household inverters (5–12kW) and available in three capacities — 15kWh, 16kWh and 20kWh — with support for multiple-unit parallel expansion as your energy needs grow.

View SpecificationsWhere Home Battery Storage Fits Your Life
Three core scenarios covered by the HJ series.
Solar Self-Consumption
Store excess daytime solar generation and use it in the evening — maximizing the value of your existing solar panels through peak-valley arbitrage.
Backup Power
Keep critical household loads — refrigerators, lighting, medical equipment — running during grid outages.
Off-Grid / Remote Home
Pair with our BNSA industrial DC-AC inverter series for standalone power in areas with unreliable or no grid supply.
UL / CE Certified Home Battery Storage
Every HJ series home battery is manufactured and independently certified to UL and CE battery safety standards, backed by a three-level BMS safety architecture — giving homeowners and installers confidence in every installation.
- UL certified battery safety architecture
- CE certified for EU market compliance
- Three-level BMS real-time monitoring
- ≥6,000 cycle standard cycle life
- 10-year warranty, 24-hour service response
HJ-Series Home Storage — Case Studies
We don't yet have a published case study specific to the HJ-series battery itself. Our companion BNSA-KD industrial DC-AC inverter, which pairs directly with HJ-series storage for standalone power, does have a published reference project. See all projects for our full list of installations, or contact us to discuss reference sites for HJ-series deployments.
Home Energy Storage — Frequently Asked Questions
Common questions from homeowners and installers evaluating the HJ-series.
Which HJ-series capacity is right for my home?
HJ-15KWh (51.2V / 280Ah) suits smaller homes or apartments with moderate daily energy use, matching 5–8kW inverters. HJ-16KWh (51.2V / 314Ah) is a mid-range option matching 5–10kW inverters. HJ-20KWh (51.2V / 390Ah), our most popular model, matches 8–12kW inverters and suits single-family homes and villas. Contact our team if you're not sure which fits your usage.
What battery chemistry does the HJ-series use, and is it safe?
All HJ-series models use Lithium Iron Phosphate (LiFePO4) cells, which are inherently more thermally stable than other lithium chemistries. Every unit is independently certified to UL and CE battery safety standards, backed by a three-level BMS real-time monitoring architecture.
Can HJ-series storage provide backup power during a grid outage?
Yes. HJ-series is built for backup power — keeping critical household loads such as refrigerators, lighting and medical equipment running during grid outages.
Can I expand capacity later by adding more units?
Yes. HJ-series supports multiple-unit parallel expansion, so you can start with one unit and add more as your household's energy needs grow.
Do I need existing solar panels to use HJ-series storage?
No, though it's most commonly paired with solar for self-consumption and peak-valley arbitrage. HJ-series is compatible with mainstream household inverters (5–12kW) and works alongside your existing solar setup without replacing your inverter.
What's the warranty and expected service life?
HJ-series is backed by a 10-year warranty and rated for ≥6,000 standard charge/discharge cycles, with 24-hour service response.
Can HJ-series be used in remote or off-grid areas?
Yes. Pair HJ-series with our BNSA industrial DC-AC inverter series for standalone power in areas with unreliable or no grid supply.
