This listing covers the BigBattery ETHOS off-grid power system, paired with a 12000XP V2 inverter. The DATA provided to us does not break out per-unit voltage, Ah, or discharge specs for the individual ETHOS battery modules or the inverter — we are flagging that below rather than guessing.
Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
What This System Is
The ETHOS platform is an off-grid energy storage system from BigBattery, scaling from 10.24 kWh up to 92.16 kWh depending on how many battery modules you configure. This particular listing pairs the ETHOS batteries with a 12000XP V2 inverter. Chemistry, cycle life, BMS discharge/charge limits, dimensions, weight, and terminal type were not included in the DATA provided for this specific product page — these are called out as [NEEDS VERIFICATION] rather than assumed from other ETHOS listings.
Battery Characteristics
Chemistry: [NEEDS VERIFICATION] — the source data for this listing does not state the cell chemistry, though ETHOS is a BigBattery product line. Do not assume LiFePO4 from the product name alone; confirm via the Resources tab before ordering.
Group Size / Form Factor: [NEEDS VERIFICATION]
Wiring & Configuration Limits (Series/Parallel)
The capacity range listed for this system — 10.24 kWh to 92.16 kWh — indicates a modular, expandable design. However, the DATA provided does not specify the exact number of modules per series string, maximum parallel strings, or voltage per module. [NEEDS VERIFICATION]
Do not wire modules of different ages, capacities, or firmware revisions together in the same series/parallel bank until you've confirmed compatibility using the manufacturer documentation referenced above. Mixing mismatched modules risks cell imbalance and premature BMS lockout.
Pro-Installer Tip
Series/parallel expansion on modular LiFePO4 systems is where most field failures start. If you add a battery module from a different production batch without checking its resting voltage against the existing bank, you risk forcing the BMS into a protective lockout the first time the system tries to balance the string. Before connecting a new module, rest it for 30 minutes and check open-circuit voltage with a shunt-based battery monitor — match it within the manufacturer's stated tolerance before you close the loop. Keep every module in the bank operating within the same depth-of-discharge target (commonly 80–100% DoD for lithium systems) so no single module ages faster than the rest of the bank.
Key Benefits
- Scalable capacity from 10.24 kWh to 92.16 kWh to match load growth over time.
- Pairs with the 12000XP V2 inverter as a matched off-grid kit.
- Single SKU (K0710-V) covers a 10-variation configurable build.

Options & SKUs
| Variant | SKU | Price (USD) |
|---|---|---|
| variable parent (10 variations) | K0710-V | 4304.99 |
This listing's parent SKU represents a configurable build with 10 underlying variations. Per-variation kWh, pricing, and component breakdowns were not itemized in the DATA provided — confirm the exact configuration and price for your target capacity before ordering.
Compatibility & Fitment
This system is sold as an ETHOS battery plus 12000XP V2 inverter kit. It is intended for off-grid and battery-backup applications where the two components are used together as configured.
Not confirmed compatible with other inverter models outside this kit — do not substitute a different inverter without verifying voltage window and communication protocol against the ETHOS battery's BMS. Charger/inverter requirements, cold-weather charging protection, and low-temperature disconnect behavior were not stated in the DATA provided; treat charging equipment compatibility as [NEEDS VERIFICATION] until confirmed via the Resources tab.
Standard lead-acid chargers are not recommended for lithium-based systems unless the charger is explicitly rated for LiFePO4 charge profiles — confirm chemistry and charger compatibility before use.
FAQ
What capacity range does this ETHOS system cover?
This system scales from 10.24 kWh to 92.16 kWh depending on configuration.
What inverter is included with this kit?
This listing pairs the ETHOS battery with a 12000XP V2 inverter.
