Ideal for homes that want free power at night and protection for appliances from voltage dips and outages
Home Battery
A battery stores the power you generate during the day for use at night and backs you up during outages. Every model below uses LFP (lithium iron phosphate) cells, which are safer and longer-lasting than ordinary lithium. All figures are from manufacturer datasheets
Expandable up to 21 kWh in one cabinet
Best for: Homes that want to start small and expand, with one brand looking after the whole system
314Ah cells rated for 10,000 cycles
A home battery stores surplus power produced during the day for use at night or when electricity is expensive, so you rely less on the grid and save more than with a standard solar system
During an outage the system switches to battery power automatically, so your home keeps running and appliances and critical equipment are protected from dips and surges
The modular design lets you start with the right capacity and add more later as your usage changes, without replacing the whole system
A 5 kWh battery can back up basic loads (lights, fridge, Wi-Fi) for 4–6 hours, or 2–3 hours with one air conditioner running. Batteries of 10 kWh and up can last all night
Lithium Iron Phosphate (LFP) batteries last 6,000–10,000 cycles, or about 10–15 years in normal use, with at least 70% capacity guaranteed over 10 years
A 5 kWh battery costs about 80,000–120,000 baht (installed) and a 10 kWh battery 150,000–220,000 baht, depending on brand, technology and the paired inverter
Yes. If your existing inverter supports it (a hybrid inverter), a battery can be connected directly; with a string inverter you may need to switch to a hybrid inverter first. We check for free before advising
It uses safe, non-flammable LFP technology, scales modularly, works with Huawei SUN2000 inverters, manages energy automatically with AI and has a 10-year warranty
Best for: Homes that want the most charge cycles and an EV charger built into the same system
Inverter + battery in one unit
Best for: Homes with limited installation space that want a quick, all-in-one system
5.12 kWh modules — add more as budget allows
Best for: Tight starting budget — start with one module and add more later
16 kWh for homes with heavy usage
Best for: Large homes with heavy night-time use, or whole-home backup
Connects to your existing system — no inverter replacement needed
Best for: Homes that already have solar and want to add a battery later without tearing out the existing system
