A battery is useful for backup power. Under Solar ATAP it adds only a modest saving: unused export credit is forfeited at the end of each billing period, and each stored kWh is worth only the gap between the RM 0.4443 you avoid and the RM 0.2703 export credit. Trexon offers Huawei LUNA2000 and SolisStorage; it does not offer Tesla Powerwall or BYD. So which battery should you choose? This guide compares the top three contenders in the Malaysian market: Tesla Powerwall 3, Huawei LUNA 2000, and BYD B-Box Premium.
The Big Three: Quick Comparison Table
| Feature | Tesla Powerwall 3 | Huawei LUNA 2000 | BYD B-Box Premium |
|---|---|---|---|
| Usable Capacity | 13.5 kWh | 5–30 kWh (modular; Trexon catalogue: 7 / 14 kWh) | 5.1–22.1 kWh (Modular) |
| Power Output | 11.5 kW (Continuous) | 2.5 kW per 5kWh module | 5 kW – 10 kW |
| Battery Chemistry | LiFePO4 (LFP) | LiFePO4 (LFP) | LiFePO4 (LFP) |
| Warranty | 10 Years | 10 Years | 10 Years |
| Price (Installed; LUNA = Trexon catalogue, others = market estimate, not stocked) | RM 35,000 – 55,000 | RM 23,999 (7 kWh) / RM 35,999 (14 kWh) | RM 18,000 – RM 40,000 |
| Inverter Included? | Yes (Hybrid) | No (Requires Huawei Inverter) | No (Compatible with many) |
1. Tesla Powerwall 3: The All-In-One Powerhouse
The Tesla Powerwall 3 is a widely known battery. It is a fully integrated system with a built-in solar inverter, making it a simple installation for new solar setups.
Pros:
- High Power Output: 11.5 kW means it can run almost any appliance in a Malaysian home, including multiple 2HP air conditioners simultaneously.
- Seamless Integration: The Tesla App is well regarded for energy monitoring.
- Space Efficient: Slim design that looks great on modern Malaysian homes.
Cons:
- Fixed Size: You cannot start small. It is 13.5 kWh or nothing.
- Availability: Not offered by Trexon.
2. Huawei LUNA 2000: The Modular Smart Choice
Huawei inverters are widely installed in Malaysia, and the LUNA 2000 battery is designed to work with their SUN2000 series inverters.
Pros:
- Modularity: Start with 5 kWh and add more modules as your budget allows.
- LFP Chemistry: Cobalt-free and durable, often rated for 4,000+ cycles.
- Smart String Management: Each 5kWh module has a built-in optimizer, meaning a weak cell doesn't drag down the whole system.
Cons:
- Vendor Lock-in: Only works with Huawei inverters.
- Lower Peak Power: You need at least 10 kWh (2 modules) to get 5 kW of continuous power.
3. BYD B-Box Premium (HVS/HVM): The Flexible Workhorse
BYD is a major manufacturer of LFP batteries. Their B-Box Premium series is a common choice for "open" systems where you want to mix and match brands.
Pros:
- High Compatibility: Works with SMA, Sungrow, Victron, and GoodWe inverters.
- Value for Money: Competitive cost per kWh for mid-range capacities (10-15 kWh).
Cons:
- Industrial Aesthetic: Looks more like a server rack than a piece of home decor.
- Complex Setup: Requires expert configuration to sync with third-party inverters.
Which Battery Wins for Your Malaysian Home?
For New High-End Installs: Tesla Powerwall 3
If you are building a new luxury home and want high power output and a polished app, the Powerwall 3 is a strong option (Trexon does not offer it).
For Retrofits & Value: Huawei LUNA 2000
If you already have a Huawei inverter, adding a LUNA module is a logical, cost-effective upgrade (Trexon offers the LUNA2000).
For Off-Grid or Custom Systems: BYD B-Box
If you are building a custom off-grid system or want to use industrial-grade components from brands like Victron, BYD is a common choice.
Conclusion: Choose by Your Needs
Storage is worth adding if you want backup power or have evening-heavy use. Companies installing battery storage may claim the GITA Asset allowance (Tier 1, 100% of qualifying capex, subject to MGTC verification), but it must be commissioned and submitted to MGTC by 31 December 2026; homeowners are not eligible for GITA. Ask for a current battery quotation and compare it with the savings you expect.
