5kWh Floor Mounted Solar Battery: Compare 5kWh, 10kWh and 15kWh

A 5kWh floor mounted solar battery is typically considered for essential backup loads and solar self-consumption. The 10kWh and 15kWh versions extend the energy window for larger loads or longer runtime. Select the battery from usable energy, average and surge load, inverter limits, PV recharge and the required reserve state of charge—not from nameplate kWh alone.

OptionRated capacityDimensions / weightPlanning fit
5kWh51.2 V, 100 Ah760 × 480 × 215 mm / 50 kgEssential circuits, shorter backup targets and modest evening solar use.
10kWh51.2 V, 200 Ah775 × 480 × 245 mm / 88 kgLonger backup or a wider household self-consumption window.
15kWh51.2 V, 300 Ah920 × 485 × 255 mm / 120 kgHigher daily energy use, longer runtime or planned load growth.

The table is a quick comparison of the listed models. Confirm the final datasheet, usable capacity, continuous current, accessories and warranty conditions for the exact quotation.

Runtime, Inverter Compatibility and Installation Checks

How to estimate battery runtime

Start with usable battery energy (kWh) ÷ average load (kW). For example, if the approved usable energy is 4.5kWh and the average protected load is 0.5kW, the baseline is about 9 hours. Then allow for inverter loss, reserve SOC, temperature, battery aging and motor starting loads. A refrigerator, pump or air conditioner can require much more starting power than its average consumption suggests.

Will it work with a 48V inverter?

Nominal voltage is only the first check. Confirm the inverter's battery voltage window, charge and discharge current, CAN or RS485 protocol, cable pinout, firmware, low-SOC behavior and approved battery model. A matching connector or brand logo does not prove communication compatibility. Compare the solar inverter range and send the exact inverter model before ordering.

What should be checked at the installation location?

Verify floor loading, cabinet dimensions, service clearance, cable route, protection devices, ventilation, ambient temperature and access for delivery. Confirm whether future batteries may be paralleled and whether mixed ages, capacities or firmware versions are allowed.

Information to Send for a Floor-Mounted Battery Quote

  • Installation country and single-phase or three-phase supply.
  • Inverter brand, exact model, firmware and required communication protocol.
  • Essential-load list, largest starting load and target backup hours.
  • PV array size, expected recharge window and operating mode.
  • Indoor or sheltered location, temperature range and available floor space.
  • Required capacity, expansion plan, quantity and destination.
  • Certification, shipping, labeling, OEM and warranty requirements.

Floor-Mounted Solar Battery FAQ

How do I choose between 5kWh, 10kWh and 15kWh?

Calculate usable energy from the protected loads and required hours, then check inverter power, surge current and PV recharge. Keep a reserve for low-SOC limits, aging and weather instead of sizing to the exact nameplate capacity.

Can the battery capacity be expanded later?

Expansion may be possible, but the quoted model, BMS, firmware, cable set and inverter must support the planned parallel configuration. Confirm the maximum quantity and rules before the first installation.

What does the listed battery price include?

Confirm whether the quote covers the battery, base or cabinet, communication and power cables, breakers or fuses, inverter, monitoring, freight, tax, installation and commissioning. Comparing the same supply boundary prevents misleading price comparisons.
