EV Charger Questions

7 questions

Possibly — and this is the question most buyers skip entirely. A Level 2 home charger requires a dedicated 240V circuit drawing 30–50 amps. Under NEC Article 625, EV chargers are classified as continuous loads, which means the circuit must be sized to 125% of the charger's rated amperage.

Real cost alertPanel upgrades add $1,500–$3,500. In Massachusetts, a full service upgrade can reach $4,500–$6,000. Total installed cost: $800–$2,500 with a ready panel, $3,000–$5,000+ with panel work.

Before ordering, have your electrician perform a panel load calculation. Our Build Your System guide walks through this as Step 1.

32A (7.7kW): ~25–30 miles/hour. Fine for overnight charging under 60–70 miles/day.

40A (9.6kW): Most common residential choice. Charges most EVs full in 6–8 hours overnight.

48A (11.5kW): Fastest Level 2. Best for large-battery vehicles or two-EV households.

The wiring truth most installers don't volunteerYour charger's speed is set by your wiring. A 48A charger on undersized conductors charges at whatever the wire can safely carry. Long runs require a voltage drop calculation.

Yes, in most jurisdictions. A Level 2 charger involves new 240V electrical work, triggering permit requirements under most local building codes.

What happens without a permitAn unpermitted installation can void homeowner's insurance, complicate a home sale, and result in fines. A permit typically costs $100–$200 and protects a $1,000–$3,000+ investment.

Level 1 (120V): ~5 miles/hour. No install required but too slow for most daily drivers.

Level 2 (240V): What we sell. 20–35+ miles/hour. Requires a dedicated circuit and professional installation.

DC Fast Charging: Commercial-grade. Requires three-phase power and utility approval — not practical for residential.

Yes. A grid-tied solar system earns net metering credits you use to charge at night. For direct solar-to-EV charging, you need a smart charger with EMS integration or a hybrid inverter + battery system.

The most common mistake: planning for 4 ports instead of 40. Infrastructure decisions made today determine what it costs to scale later.

The decision that saves or costs tens of thousandsLoad management software lets more ports share a circuit. Make-ready conduit and wiring turns future expansion from a construction project into a plug-in.

A straightforward installation typically takes 2–4 hours. Add time for long wiring runs, panel upgrades, permit processing (1–5 business days), or trench runs for outdoor installations.

Solar & Generator Questions

5 questions

Technically yes — but most refrigerators require 1,200–2,400 surge watts when the compressor starts. A generator must handle that surge, not just the running load.

The "runs a refrigerator" claim decodedRuntime on a single charge is typically 8–15 hours, not indefinitely. 1,800–2,000W is the practical minimum for one refrigerator.
→ Browse solar generators

Rated kWh is total capacity. Usable kWh is what you can actually draw. Depth of Discharge (80–90%) and inverter efficiency loss (5–15%) reduce the headline number. Always ask for usable kWh at rated DoD.

Not with a standard grid-tied system. Grid-tied inverters shut down when the grid fails — by regulation. Your panels generate but the inverter disconnects.

The outage surprise most solar homeowners don't know until it happensThe fix: a hybrid inverter + battery system with an automatic transfer switch.
→ See battery + inverter systems

Portable (1–5kWh): Best for short outages and select appliances. Not for central AC, electric dryers, or hardwired 240V loads.

Home battery system (5–40+ kWh): Whole-home or critical-circuit coverage for 24–72+ hours. Pairs with inverter + ATS for seamless grid-failure response.

→ Size your system

A 2kWh generator with 400W solar input recharges in roughly 1–1.5 days under 4–5 peak sun hours. In New England: 3.5–4.5 hours summer / 2–3 hours winter. Plan for solar as a supplement, not the only input.

Battery Backup Questions

5 questions

Start with a load calculation, not a product page. List critical loads, estimate daily kWh, define your target backup duration, then size battery + inverter to match.

The most common sizing mistakeA buyer gets a 10kWh system for "whole home backup for 24 hours" — but fridge + sump + lighting + medical draws 2kW continuously. 24 hrs x 2kW = 48kWh. Load priority planning beats buying more capacity.
→ Size your battery system

"Whole home backup" means the battery can be connected to every circuit. How long it lasts depends entirely on your load profile.

Whole home backup is a connection option — not a capacity guaranteeA 10kWh battery running AC + water heater + oven lasts ~83 minutes. The same battery on critical circuits only lasts 12–20+ hours.

A standard inverter converts solar DC to AC and shuts off when the grid fails. No battery capability.

A hybrid inverter manages battery charge/discharge and operates in island mode during outages. Verify your current inverter is hybrid-capable before purchasing batteries.

Quality LiFePO4 systems are rated for 3,000–6,000+ cycles, typically 10–15+ years before capacity degrades to 80%. Manufacturer warranties on products we carry typically cover 10 years on battery capacity.

Yes. Battery systems involve high-voltage DC wiring, inverter interconnection, and automatic transfer switches. DIY installation voids warranties, violates utility agreements, and fails permit inspection.
