Power use in a weekender is rarely predictable. A property might sit empty for weeks, then need to run everything the moment someone arrives. The system needs to handle both without wasting money on unnecessary capacity.
Yes — where the vehicle and charger support bidirectional (vehicle-to-home) operation.
A V2H charger lets the car battery feed the home during extended cloud, peak evening cooking load, or when the home bank is low — then recharge from solar when production returns.
Not every EV or charger supports this yet. Check vehicle spec and charger compatibility before assuming V2H.
On large 5-bed properties with events or extended family, an EV adds a meaningful second storage reserve beyond the home battery bank — worth planning into system design as the technology becomes more common.
Yes. Every 100UP system is sized for maximum occupancy — not just who’s living there today.
The 100UP Way: 5 kWh for the house, plus 5 kWh per person by bedroom capacity. A 4-bedroom install is engineered for up to eight people — heating, hot water, cooking, appliances running together.
That covers family visits, Airbnb guests, changing household size, and resale — a buyer isn’t inheriting a system that only worked for two people.
Full house, full load — that’s the scenario we design for.
If you might add an EV, more appliances, more people, or heavier heating/cooling in the next 3–5 years, plan expansion now — retrofitting an undersized platform costs more than sizing the infrastructure correctly upfront.
Prevention approach:
Simpler only makes sense when usage is genuinely stable — no family change, no EV, no new heavy loads. Most households grow energy demand over time.
100UP’s default: plan for expansion. Lower cost now, fewer expensive regrets later.
Yes. Modern off-grid systems need little attention when the property is vacant. Solar keeps the battery topped up; the BMS balances cells — no manual wake-up routine.
Before you travel, check remote monitoring: state of charge, recent production, any alerts. You arrive knowing power is ready.
Unlike some legacy setups, there’s no awkward cold-start — depending on configuration, the system is already live or one switch away.
That’s why weekender and short-stay properties suit off-grid well — the system works between visits without babysitting.
Split solar from storage in the sizing decision.
Example: a 3-bed property might launch with 15 kW solar, 54 kWh storage, and 16 kW inverter capacity — then add battery modules when occupancy rises or EV charging lands. Solar and inverter headroom are already there.
You buy flexibility now without paying for kWh you don’t need yet.
