What Is a Home Storage Battery?
A home storage battery stores excess PV energy for night use and provides backup during outages. Typical systems pair 48V LiFePO4 packs with hybrid inverters for self-consumption, backup power, and peak-shaving.
Saftec supports brand customization, enclosure options, and BMS communication (RS485/CAN) for mainstream 48V inverters.

Use cases: Space-limited homes needing compact backup + PV storage
Notes: Wall bracket mounting; IP grade and enclosure color/branding customizable
Applications of Home Storage Batteries
- Residential solar self-consumption – Store daytime PV to cut evening grid use.
- Backup during outages – Keep critical circuits (lighting, Wi-Fi, fridge, pumps) alive.
- Peak-shaving / time-of-use – Charge off-peak, discharge at high tariffs to reduce bills.
- Off-grid cabins / farms – Core storage for remote sites without reliable grid.
- Small commercial stores / offices – Reduce demand charges and improve resilience.
- Scalable whole-home backup – Parallel multiple units to support larger inverters and loads.

Common Pitfalls When Purchasing Home Storage Batteries
1. Overlooking Battery Lifespan & Cycle Life
Pitfall: Many buyers don’t realize that cheap batteries often have shorter lifespans, leading to more frequent replacements and higher long-term costs.
Solution: Saftec offers LiFePO4 batteries with 6,000 cycles, ensuring long-lasting performance and reducing the frequency of replacements, saving you money in the long run.
2. Ignoring Certification and Compliance
Pitfall: Not checking safety certifications such as UN38.3, IEC, and RoHS can lead to issues with shipping, installation, and safety standards.
Solution: Saftec batteries are UN38.3, IEC 62133, and RoHS certified, so you can be confident in their global compliance, ensuring safe use and smooth customs clearance.
3. Choosing Incompatible Battery Sizes or Voltages
Pitfall: Many buyers pick batteries without considering their system compatibility, like voltage, capacity, or how they integrate with their solar inverters.
Solution: Saftec offers OEM/ODM services, allowing for customized configurations (12V, 24V, 48V) and BMS integration, ensuring the perfect fit for your energy system.
4. Failing to Plan for Battery Expansion
Pitfall: Underestimating future energy needs and failing to select a modular solution can result in having to buy an entirely new system as energy demands grow.
Solution: Saftec’s stackable batteries are designed for scalability, allowing you to add capacity easily as your energy needs grow without replacing the whole system.
5. Ignoring Proper Installation and Maintenance Requirements
Pitfall: Improper installation or lack of maintenance can affect battery performance and safety, leading to failures or lower capacity.
Solution: Saftec offers installation guidance, technical support, and low-maintenance solutions (like LiFePO4 chemistry), so you don’t have to worry about frequent upkeep or safety concerns.
6. Choosing the Cheapest Option Without Considering Total Cost of Ownership (TCO)
Pitfall: Many buyers focus only on upfront cost, ignoring how long-term performance, maintenance, and replacement will affect the total cost.
Solution: Saftec offers cost-effective LiFePO4 batteries that provide better ROI in the long run, thanks to their longer lifespan, high efficiency, and low maintenance.
Ask Us Anything
How many kWh does a typical home need?
Most residential systems ship at 5–15 kWh. For critical loads, 7–10 kWh is common; whole-home backup often uses 10–20 kWh depending on appliances and backup hours.
How long will a 10 kWh battery last during an outage?
It depends on average load. Example:
~0.8 kW average load → ≈12–13 hours
~1.5 kW → ≈6–7 hours
(Exclude inverter losses and surges when planning; size with margin.)
Can I expand later? Any rules?
Yes. Use the same voltage and similar capacity modules; adding within 6–12 months keeps pack aging aligned. Systems support multiple parallel units per project spec.
What charging and operating temperatures apply?
Typical LiFePO4 ranges: charge 0–45 °C, discharge −20–60 °C. For sub-zero charging, choose low-temperature BMS / self-heating options.
Are Saftec batteries compatible with my inverter?
Saftec 48V packs integrate with mainstream 48V hybrid inverters using RS485/CAN. Share your inverter model/protocol and we’ll match BMS settings.
Stackable vs. Powerwall — which should I choose?
Choose Stackable if you value easy capacity expansion and floor-standing serviceability. Choose Powerwall for space-saving, wall-mount installs and sleek home aesthetics.
What certifications and documents do I need for shipping and installation?
Projects typically require UN38.3 test reports, MSDS, and RoHS; stationary storage commonly references IEC 62619 (or 62133 for certain applications). Saftec supplies the full pack.
What lifetime should I expect?
Under standard test conditions (25 °C, 0.5C, 80% DoD), Saftec packs reach up to 6,000 cycles. Real-world life varies with DoD, temperature, and charge profile; daily cycling usually implies 10+ years.
Where should I install the battery? Indoor or outdoor?
Prefer dry, ventilated indoor locations away from heat sources. Outdoor use requires appropriate IP-rated enclosures and adherence to local electrical codes.
