On 100UP installs for full-time or high-value use, redundancy is standard — not an optional extra.
TwinGuard: Dual independent inverters in parallel — one fails, the other carries load.
TripleShield: Three independent inverter/battery sections — no single component owns the whole system.
Modular batteries: Per-module management so one unit fault doesn’t shut the bank.
Without redundancy, one inverter or battery fault blacks out the property. With it, you get reduced capacity, not zero power. That trade-off costs more upfront — and it’s what full-time off-grid living needs.
