Does this kit include everything I need to install it?
Every major component, including the enclosed battery cabinet that on most systems is a separate purchase: the hybrid inverter, all six batteries, all twenty-eight panels, three PV breakers, three sets of solar extension cables, the DC breaker and the battery cabling. What varies is the building side of the job, and on an array this size that side is significant: rail racking across one or more roof planes or a ground mount structure, conduit, junction boxes, building wire, a critical loads panel, and labor. If you're interconnecting, add the utility application, any protective equipment your utility specifies, and the electrician's time. Those depend on your structure, your utility and your local code, which is why we spec them per site. Tell us about your install and we'll list exactly what yours needs.
Do I have to connect it to the grid?
No. The same kit runs fully off-grid, and at 12.6kW of array with 30.72kWh of storage it does that well. You lose the ability to draw from the utility on a bad week and you lose any export credit, but you also skip the interconnection agreement entirely. Plenty of customers buy this kit for exactly that reason.
Will my utility approve a 12.6kW array?
Usually, but it depends on your territory and sometimes on your service size. Some utilities apply a supplemental review above a certain system size, some cap export at your historical consumption, and some require additional protective equipment. The inverter's UL1741 and UL1699B listings clear the equipment side of that question. The rest is local, and it's worth a call to your utility before you order rather than after.
How should the panels be wired?
Three strings, one per MPPT input: ten panels on the first tracker and nine on each of the other two. Ten in series operate near 300V and nine near 270V, both well inside the 70 to 540V window, at 16A per string. Don't parallel two strings onto a single tracker, because two of these strings is 32A against a 30A limit on the first input and 22A on the other two. Three independent trackers also means you can point the three strings in three different directions without penalty, which is often what a 28 panel array needs.
How much energy will this generate daily?
The 12.6kW array produces roughly 50 to 63kWh per day at 4 to 5 peak sun hours, plus whatever the rear faces add. For most properties that is well above consumption, which is the intent: the surplus offsets or exports rather than sitting idle. Actual output depends on your location, season, panel angle and shading.
Can the battery bank keep up with the inverter?
The six-battery bank provides 30.72kWh of nominal storage. The inverter provides 11.4kW of nominal AC output and has a battery discharge power limit of 10kW before conversion losses. Actual output depends on battery conditions, system settings, and installation.
Can I install this myself?
We recommend professional installation. This kit includes twenty-eight panels, an inverter weighing 103.6 lbs, and six batteries in an enclosed cabinet. Your installer should handle mounting and electrical connections according to the manufacturer’s instructions and local requirements.
Is LiFePO4 safe?
It's the safest widely available lithium chemistry, with strong thermal stability, long service life and minimal maintenance. These cells carry UL1973 and UN38.3, and every battery includes BMS protection against overcharge, deep discharge, overheating, overload and short circuit.
