Specifications Breakdown
Usable Storage Capacity
The LG Energy Solution RESU 10H provides 9.3 kWh of usable capacity (9.8 kWh total, 95% DoD), while the Panasonic EverVolt 2.0 EVDC-105 offers 13.6 kWh usable (13.6 kWh total, 100% DoD). At an average essential-load consumption rate of 750 watts, the LG Energy Solution RESU 10H provides approximately 12.4 hours of backup versus 18.1 hours for the Panasonic EverVolt 2.0 EVDC-105. The Panasonic EverVolt 2.0 EVDC-105's 4.3 kWh capacity advantage translates to roughly 6 additional hours of essential-load backup during a grid outage. The LG Energy Solution RESU 10H is scalable up to 2 units (19 kWh total), while the Panasonic EverVolt 2.0 EVDC-105 scales up to 4 units (54 kWh total).
Power Output
The LG Energy Solution RESU 10H delivers 5 kW continuous and 7 kW peak power, while the Panasonic EverVolt 2.0 EVDC-105 provides 7.6 kW continuous and 9.6 kW peak. The Panasonic EverVolt 2.0 EVDC-105's higher continuous output means it can simultaneously power more demanding appliances during an outage. A central air conditioner typically draws 3-5 kW, a refrigerator 0.1-0.2 kW, and an EV Level 2 charger 7-11 kW. Peak power rating matters for motor-driven loads with high startup current, such as air conditioners, well pumps, and sump pumps. The Panasonic EverVolt 2.0 EVDC-105's 9.6 kW peak is suitable for lighter startup loads.
Battery Chemistry & Cycle Life
The LG Energy Solution RESU 10H uses NMC chemistry with a rated cycle life of 4,000 cycles (approximately 11.0 years of daily cycling), while the Panasonic EverVolt 2.0 EVDC-105 uses LFP with 6,000 cycles (approximately 16.4 years). LFP (Lithium Iron Phosphate) offers superior thermal stability with zero risk of thermal runaway, longer cycle life, no cobalt dependency, and tolerance for 100% depth of discharge. NMC (Nickel Manganese Cobalt) provides higher energy density in a smaller and lighter package but has shorter cycle life and requires more conservative depth-of-discharge management. The Panasonic EverVolt 2.0 EVDC-105's additional 2,000 cycles translates to approximately 5.5 more years of daily use before reaching the rated end of life.
Round-Trip Efficiency
The LG Energy Solution RESU 10H achieves 94.5% round-trip efficiency versus 93.5% for the Panasonic EverVolt 2.0 EVDC-105. This means for every 10 kWh of solar energy stored in the LG Energy Solution RESU 10H, 9.4 kWh is recoverable, compared to 9.3 kWh for the other. Over 10 years of daily cycling with 15 kWh average daily throughput, the more efficient battery saves approximately $82 in energy that would otherwise be lost as heat (at $0.15/kWh average retail rate). Higher round-trip efficiency is especially valuable in time-of-use rate environments where you are storing cheap off-peak energy for expensive peak-hour consumption.
Warranty & Long-Term Protection
The LG Energy Solution RESU 10H carries a 10-year warranty and 22.4 MWh throughput, while the Panasonic EverVolt 2.0 EVDC-105 offers 15 years. The Panasonic EverVolt 2.0 EVDC-105 provides 5 additional years of manufacturer protection against capacity degradation and defects. Battery warranties typically guarantee the unit will retain 60-70% of original capacity by end of warranty, so the length of coverage directly impacts your financial risk over the system's lifetime.
