Battery Backup Price Calculator

Build your system

Pick the size. See the price.

No packages, no bundles you don't need. Choose an inverter, choose a battery line, stack as many batteries as you want — the price updates as you go. Everything is Growatt, and every price includes the equipment, the installation.

1 Inverter capacity

3 kWone leg 8 kWboth legs 12 kWboth legs

Your main breaker sets the size. Multiply its amp rating by 120 for one leg, or by 240 for the whole house: a two-pole 30 A main is 3.6 kW per leg and 7.2 kW in total, so the 8 kW covers it. A 40 A main wants the 12 kW. The 3 kW is the entry system: it covers one 120 V leg on a 30 A service and no more. Always round up, never down.

Not sure? Send us a photo of your master breaker — here it's usually right under or beside the CFE meter at the service entrance, not inside the house. We'll read it in a minute; it's the easiest question we get all week.

2 How many inverters

3 Battery line

Compact Growatt AXE 5.0 kWh · 92% DoD · 5-yr warranty (10 optional). Tool-free stacking tower, no cabling between modules. Caps at 6 kW output however many you stack, so it suits the 3 and 6 kW systems only. Scales Growatt Hope 5.12 kWh · 98% DoD · 6,000+ cycles · 5-yr warranty. 5.12 kW per module and it keeps scaling, so it is the only line that can carry the 8 and 12 kW systems.

These hours are how long the batteries last at that draw — not at the inverter's full rating. Whether the A/C is on the backup is a decision you make at install, and it is the whole difference between the two.

The price calculator needs JavaScript. Send us a WhatsApp with your town and what you'd like to keep running and we'll price it for you the same day — +52 984 212 9876.

Prices are in Mexican pesos, installed — equipment, mounting, wiring and handover, plus tax and the fixed DC breaker fee below. Runtime figures assume a steady average draw and 90% usable capacity; your real numbers come from the load audit. Homes needing long cable runs, panel replacement or three-phase service are quoted separately, and we tell you that on the site visit rather than in the invoice.
