Frequently Asked Questions

AGAIC POWER BSM715 HJT (Heterojunction) solar panels achieve up to 23.5% module efficiency — among the highest available for residential and commercial applications. This translates to more electricity per square meter compared to conventional PERC panels (typically 20-21.5%).

HJT (Heterojunction) offers superior temperature coefficient (-0.26%/°C), higher bifaciality (90-95%), simpler manufacturing, and lower carbon footprint. TOPCon currently has a cost advantage due to easier factory conversion from PERC lines. For hot climates, limited roof space, or ground-mount bifacial installations, HJT wins. For tight budgets in moderate climates, TOPCon is competitive. Read our deep-dive comparison →

All AGAIC POWER solar panels include a 10-year product warranty and a 25-year linear performance warranty, guaranteeing at least 87% of rated power output after 25 years of operation. This exceeds the industry standard 80% guarantee.

Our panels are certified to TÜV Rheinland, IEC 61215, IEC 61730, UL 61730, and CE standards. They also comply with ISO 9001:2015 quality management and RoHS environmental requirements. This multi-certification portfolio ensures compliance for installations in virtually any country.

Yes. The BSM715 series is rated for 5400Pa mechanical load resistance (approximately 550 kg/m²), suitable for heavy snow loads, strong winds, and harsh climates. The reinforced aluminum frame and tempered glass construction ensure decades of durability.

Use our free AgaicDesign tool — draw your roof, enter your location and electricity bill, and the tool automatically calculates the optimal number and placement of panels. A typical 5kW residential system requires approximately 15-18 panels (depending on model). Start designing →

All AGAIC POWER batteries use LiFePO4 (Lithium Iron Phosphate) chemistry. This is the safest lithium battery technology available — it is thermally stable, non-toxic, has virtually zero risk of thermal runaway or fire, and offers 6,000+ charge cycles. Unlike NMC (Nickel Manganese Cobalt) batteries used by some competitors, LiFePO4 does not contain cobalt and has a much longer cycle life.

AGAIC LiFePO4 batteries are rated for 6,000+ cycles at 80% depth of discharge (DoD), translating to approximately 15-20 years of daily cycling. The warranty guarantees at least 70% of original capacity after 10 years or the rated cycle count — whichever comes first. For a typical household cycling once per day, that is over 16 years of service.

We offer three main home storage systems:

• AGAIC 16.07kWh Floor-Standing Battery — Ideal for new installations with dedicated utility rooms. High capacity in a single unit.
• ELEBOX-5K-HV High Voltage Stack — Modular design (5kWh per module, stackable). Perfect for space-constrained setups or incremental expansion. Start small and add modules as your needs grow.
• AIO All-in-One System — Integrated inverter + battery in one enclosure. Simplest installation, ideal for first-time solar storage buyers.

Yes. When paired with a compatible hybrid or off-grid inverter (such as the AGAIC DAHAI HyL Series), our battery systems support full off-grid operation. The system automatically manages solar charging, battery discharge, and backup generator integration if needed. Browse off-grid kits →

Absolutely. All AGAIC battery systems support parallel connection for future expansion. The ELESHELL supports up to 15 units in parallel, and the AIO system supports up to 6 units. The ELEBOX-5K-HV stackable design allows you to add modules one at a time — no need to size everything upfront.

For most homeowners, the answer depends on three factors:

• Electricity rates — If you have time-of-use pricing (peak rates 2-3× off-peak), a battery can save hundreds per year by discharging during expensive hours.
• Backup needs — If you experience frequent outages, a battery provides peace of mind that a solar-only system cannot (grid-tied solar shuts off during blackouts).
• Solar export rates — If your utility pays very little for exported solar energy, storing it for self-consumption is more valuable than selling it cheap.

Typical payback period: 5-10 years, after which the battery provides free energy for the remainder of its 15-20 year life.

We offer three inverter series for different applications:

• DAHAI HonS Series — On-grid, 3-6kW single-phase. Best for standard residential rooftop systems.
• DAHAI HonT Series — On-grid, 8-15kW three-phase. Designed for larger homes and small commercial installations.
• DAHAI HyL Series — Hybrid (on/off-grid), 3-8kW with battery integration. For homeowners who want solar + storage + backup power in one unit.

All are pure sine wave and certified to TUV/CE/IEC/UL standards. Browse inverters →

An on-grid (grid-tied) inverter feeds solar power into your home and exports excess to the grid — but shuts down during blackouts for safety (anti-islanding). A hybrid inverter does everything an on-grid inverter does, plus it can charge a battery and power your home during grid outages (island mode). Hybrid inverters cost more upfront but provide true energy independence.

Inverter capacity should roughly match your solar array size. Common guidelines:

• 3-5kW inverter → 3-6kWp solar array (small home, 10-18 panels)
• 6-8kW inverter → 6-10kWp solar array (medium-large home, 18-30 panels)
• 10-15kW inverter → 10-18kWp solar array (large home or small commercial)

A slight DC/AC ratio of 1.1-1.3 (array slightly larger than inverter) is normal and often optimal. Use our AgaicDesign tool for precise sizing based on your roof.

AGAIC HonS/HonT on-grid inverters are not designed for battery connection. The HyL hybrid series is optimized for AGAIC batteries but uses industry-standard communication protocols (RS485, CAN, RS232, WiFi) and is compatible with most 48V LiFePO4 battery systems from major brands. Check the product specifications for detailed compatibility lists.

All DAHAI series inverters are certified to TUV/CE/IEC/UL standards, meeting grid connection requirements in Europe, North America, Africa, the Middle East, and Southeast Asia. This multi-region certification is uncommon among emerging brands and is a key differentiator for AGAIC inverters in international markets.

The best choice depends on your power needs:

• BP050B (300Wh) — Phones, tablets, laptops, LED lights, small fans. Lightweight at ~4kg.
• BP060B (307Wh) — Similar capacity with fast charging support and additional output ports.
• BP120C (1,024Wh) — Mini fridge (8-12 hours), CPAP machine (2-3 nights), multiple devices overnight. The sweet spot for weekend camping.
• BP240B (2,048Wh) — Full camping kitchen, power tools, TV + gaming, home emergency backup for refrigerator and lights. Pure sine wave 2000W output handles most household appliances.

All BP series models support three charging methods:

• AC wall outlet — Fastest. BP120C charges 0-80% in ~1.5 hours with fast charging enabled.
• Solar panels — Built-in MPPT controller. A 200W solar panel charges the BP120C in 5-6 hours of good sunlight. Compatible with most third-party solar panels (MC4 connector).
• 12V car cigarette lighter — Slowest but useful on road trips. ~8-10 hours for full charge on BP120C.

You can combine AC + solar for even faster charging on most models.

A 1,024Wh station like the BP120C can run:

• Smartphone (15Wh) → ~60 full charges
• Laptop (60Wh) → ~14 full charges
• Mini fridge (80W) → ~10 hours continuous
• CPAP machine (50W) → ~17 hours (2-3 nights without humidifier)
• LED TV (50W) → ~17 hours
• WiFi router (10W) → ~85 hours

Note: Actual runtime depends on device power draw and inverter efficiency (~85%). High-wattage appliances like heaters, kettles, or air conditioners require the 2,000Wh+ BP240B.

Yes. All BP series models use LiFePO4 battery chemistry, which is inherently safe — no thermal runaway risk, no toxic fumes, no fire hazard. They are safe to use indoors, in tents, in RVs, and around children. Each unit includes multi-layer protection: overcharge, over-discharge, short circuit, over-temperature, and over-current. They are also UN38.3 certified for air transport safety.

Solar panels, inverters, and home batteries — Yes, professional installation by a certified electrician is required for safety, local code compliance, and warranty validity. These systems involve high-voltage DC connections and grid interconnection that must be handled by qualified personnel.

Portable power stations — These are plug-and-play. No installation required — just charge and use.
