Is this a complete home backup system?

No. It is a DC battery pack. You still need a compatible hybrid or off-grid inverter, a transfer switch and wiring to power a home.

How long should the battery last?

JM rates it at 8000+ charge-discharge cycles. At one cycle a day that is well over 20 years of rated cycling, though real life depends on depth of discharge and temperature.

What is the difference between the 15 kWh and 16 kWh versions?

They are the same 51.2V LFP pack; the 16 kWh model uses 314 Ah cells instead of 300 Ah. The extra capacity is small, so pick based on what your installer can source.

Does it work off grid?

Yes, it is aimed at solar storage and off-grid use. It needs an off-grid inverter and a solar charge source sized to the pack's voltage.

What certifications does it carry?

JM lists CE, RoHS, UN38.3 and MSDS. Check that your local authority accepts these for a residential install before buying.

Can the screen and branding be customized?

Yes. JM offers OEM/ODM options including a touchscreen logo and language customization, which suits installers who resell under their own brand.
