That is a 48v 200h lithium battery, the equivalent of 4x12v 200ah lead acid batteries. And he has 2, which is the same as 8x12v 200ah lead acids. And because you can use 100% of lithium battery capacity unlike lead acis where you use only 50% capacity, it means his 2 lithium batteries are equivalent to 16 x 12v lead batteries.
FYI one 48v lithium 200ah battery has 10kwh capacity and so for 2 he has 20kwh. One 12v 200ah battery only has 4.8kwh and you can only use half of the capacity ie 2.4kwh…
GPT - Based on the details in your invoice, here’s a breakdown of the power capabilities of the system:
Inverter Power: The inverter is rated at 5.0 kVA (kilovolt-amperes). For most residential setups, a 5 kVA inverter can provide around 4 kW (kilowatts) of real power, depending on efficiency and power factor, which is enough for a small to medium household with typical appliances.
Solar Panels: You have 8 solar panels, each rated at 550 W, which totals:8×550 W=4400 W (or 4.4 kW)8 \times 550 \text{ W} = 4400 \text{ W} \text{ (or 4.4 kW)}8×550 W=4400 W (or 4.4 kW)This would provide up to 4.4 kW of solar power during peak sunlight hours, potentially generating a significant amount of daily energy.
Battery Storage: The lithium-ion battery bank is rated at 10 kWh (kilowatt-hours) at 48 V. This capacity allows you to store energy for use when sunlight isn’t available, enough to cover a reasonable amount of overnight power consumption.
Can It Fully Power a House?
For Small to Medium Houses: Yes, this setup could fully power a house if consumption is moderate (e.g., lighting, TV, small appliances, and occasional use of higher-wattage devices).
For Larger Homes: It might struggle to power larger homes or those with high-energy appliances (like electric heaters, air conditioning, or large refrigerators) for extended periods, especially at night when solar power isn’t available.
