EV Charger Software With Panel-Load Math Built In

Why EV Charger Installation Companies Choose Claver

The Fastest-Growing Electrical Category

EV charger installation is the fastest-growing residential electrical category. Every Tesla and Rivian and Ford F-150 Lightning and Hyundai Ioniq 5 owner needs a Level 2 charger at home. The IRA's 30C tax credit puts $1,000 max on the install. Most state utilities layer their own $200 to $1,500 rebates on top. The shops that win are the ones who quote on-site with all three numbers built into the price. This lets the customer see the $585 net instead of the $1,485 retail.

The shops that win do two things differently. They run the panel load calc on-site so they know whether the install fits or needs a service upgrade. This avoids a surprise $2,800 panel on Day 1. They also file the IRA and utility rebate paperwork for the customer. This lets her get the $900 of credits she is entitled to without chasing her tax preparer in April.

The on-site quote with tax credit and rebate math is the engine. Panel load calc is what protects the install from a $2,800 surprise.

When you walk Mrs. Castillo's San Francisco Marina garage on a Sunday morning her new Tesla Model Y arrives Tuesday. The proposal builds itself in the app. Photograph the existing panel which is a 200A Square D QO from 1998 install in the garage. Photograph the meter which is PG&E 200A residential service. Photograph the proposed charger location on the interior wall of the garage 6 feet from the parking spot and 32-foot cable run from panel through the wall. Photograph the planned cable route as THHN in EMT conduit through the wall to the charger location. Run the NEC 220.83 load calc for existing dwelling general lighting and appliances at 12,800 VA and existing HVAC heat strip at 9,600 VA and existing pool pump and spa at 4,400 VA. Total existing is 26,800 VA on the 200-amp service for 48,000 VA capacity. Existing usage is 56 percent of capacity. Adding 48A continuous EV circuit for 11,520 VA brings total to 38,320 VA which is 80 percent of capacity. This is under the 80 percent NEC long-duration threshold. Install fits without panel upgrade. Customer picks the Tesla Wall Connector for HOL handshake and native Tesla integration. Build the quote for $1,485 including $475 Tesla Wall Connector and $1,010 install for 32-foot 6/3 cable and EMT conduit and 60A 2-pole breaker and wall mount and 2-hour electrician labor and permit and 18 percent margin. Subtract IRA 30C tax credit of $400 and PG&E EV charger rebate of $500 for $585 net to the customer. Customer sees the breakdown. She signs digitally and pays a $371 deposit. Install Saturday morning. Tesla charges Saturday night.

The Panel Load Calc

Panel load calc is what protects the customer from a $2,800 surprise on Day 1. Most EV charger installers eyeball the panel and quote $1,485 without running the math. Then Saturday morning the tech opens the panel and realizes the 200A service is at 92 percent capacity. The existing pool pump and spa and heat-strip HVAC and Tesla charger push it over the NEC 80 percent long-duration limit. The tech tells the customer actually you need a panel upgrade first for $2,800 more. Claver runs the NEC 220.83 load calc on-site during the quote for existing dwelling load plus new 48A continuous EV circuit. If the panel is at 78 percent post-install the EV circuit fits cleanly. If at 85 percent you need a load-management device like DCC-9 and you quote it now for $385 added. If at 92 percent you need a 200-amp service upgrade and you quote it now for $2,800 added. The customer sees the all-in number on Sunday and signs Sunday. Install proceeds Saturday without surprises.

1-visit install dispatch is what makes the 2 to 3 hour install profitable. Materials arrive Friday at the customer's house including Tesla Wall Connector and 60A 2-pole Square D QO breaker and 32 feet of 6/3 NM-B cable or 6 AWG THHN and EMT conduit and wall mount bracket and hardware. Saturday morning at 8am the tech arrives and opens the panel. He installs the 60A breaker on a slot location that does not conflict with existing tandem breakers. He runs the cable from the panel through the wall to the charger location with conduit on the visible runs per local code. He mounts the wall bracket and mounts the Tesla Wall Connector on the bracket. He terminates the cable at the charger and activates the charger via the Tesla app on the customer's phone. He runs a 60-second handshake test with her Tesla Model Y and hands her the keys. The job takes 2 to 3 hours total. Customer charges that night. One trip. One tech. One $1,485 paid invoice or $585 net after rebates.

Photo and Commissioning Documentation

Photo and commissioning documentation is what gets the PG&E rebate to approve in 5 days. Claver structures every install around timestamped photos. Pre-install photos show panel and meter and proposed charger location with measurements. During-install photos show the 60A breaker installed with proper torque and no double-tapping. They show the cable run with EMT conduit where required by local code and the wall mount and charger installation and the activated charger app screen showing serial number and firmware version. Post-install photos show the installed charger with the model number and serial visible as proof of qualifying Energy Star Level 2 unit eligible for both IRA 30C and PG&E rebates. They include commissioning data for charger handshake with vehicle test and charging speed verification of 9.6kW or 11.5kW depending on hardware. Every photo geo-tags. The PDF auto-bundles to the PG&E EV charger rebate application form. The PG&E rebate inspector approves the $500 rebate in 5 days instead of 5 weeks. The customer never has to file the IRS Form 8911 herself. Your office files it as part of the install package.
