What Is a Scalable Off-Grid Solar Kit, and Who Is It For?
A solar kit for an off-grid home is a system that converts the energy from your panels into household electricity and stores it for nighttime use: a hybrid inverter plus batteries. The scalable kits from Genergy They solve the classic problem with off-grid systems, which is getting the size right: you start with a 5.1 kWh battery and can stack up to fifteen of them—76.8 kWh—whenever you need to.
Two models based on the power you need at any given time: 5,200 W (10,000 W peak) for a typical home, and 8,000 W (16,000 W peak) for large homes, water pumps, air conditioning, or small businesses. The batteries are the same in both kits: LiFePO4 with a capacity of 5,120 Wh and 4,000 charge cycles, and they stack on top of each other with the wiring included—no cabinet, no closet, and no electrician needed to expand the system. The kits do not include panels: the MPPT controller supports voltages ranging from 140 to 430 V, so you can use the ones you already have or choose your own. If you’re looking for the complete kit with panels for a grid-connected home, check out the self-consumption solar kit.

What do you need it for?
The size of the kit depends on how much you consume per day and how much at a time. Find the option that fits your situation.
Weekends and Vacations Without Internet Access
Refrigerator, lighting, water pump, television, and chargers. A 5,200-watt kit with a 5- or 10-kWh capacity covers a typical weekend, and since the house is unoccupied during the week, the battery is fully charged by Friday.
View GZE-10252 · 10 kWh →Vivir todo el año donde no llega el cable
Stove, washing machine, boiler or heat pump, and entire nights in winter. 5,200 W with 15 to 25 kWh, or 8,000 W if you also have an induction cooktop and air conditioning. And a backup generator for weeks when it’s foggy.
View GZE-20452 · 20 kWh →Pumps, milking machine, cameras, and a workshop off the grid
Motors that start simultaneously and continuous daytime power consumption. 8,000 W (16,000 W peak) with 30 to 72 kWh, expandable as the operation grows.
View GZE-30780 · 31 kWh →You don't know yet how much you're going to use
This is the most common scenario, and the one that off-grid kits handle the worst. Here, you start with an inverter and a battery, use it for a year, and add another one when needed—without throwing anything away.
View GZE-5052 · 5 kWh →UPS-style backup power for a connected home or business
The hybrid inverter also works with the grid: it charges the batteries from the grid or from solar power, and if the power goes out, the house continues to have uninterrupted power. For cameras in a store, a doctor's office, or a home office. If you're looking to save on your electric bill with solar panels, check out the self-consumption kit.
You already have panels, or a kit that didn't quite meet your needs
The MPPT supports 140 to 430 V and up to 6,000 W of capacity (10,000 W for the 8,000 W model): panels from almost any installation will work. And if you have a system Genergy, you buy the LFP 5120 Wh battery It comes loose and piles up.
It starts with one drum set and grows to fifteen
Most off-grid solar kits are sold as fixed packages: you choose 10 or 20 kWh on the first day, and that's what you're stuck with. Here, size isn't a choice—it's a string of batteries.
| What you want to cover | Usual Daily Intake | Batteries | Power |
|---|---|---|---|
| Cabin, vegetable garden, simple weekend | 3 – 5 kWh | 1 (5,1 kWh) | 5.200 W |
| Country house, for weekend use | 5 – 10 kWh | 2 (10,2 kWh) | 5.200 W |
| Vivienda habitual pequeña, sin bomba de calor | 10 – 15 kWh | 3 – 4 (15 – 20 kWh) | 5.200 W |
| Primary residence with a heat pump or well | 15 – 25 kWh | 4 – 6 (20 – 31 kWh) | 5.200 / 8.000 W |
| Large house with air conditioning and an induction cooktop | 25 – 40 kWh | 6 – 9 (31 – 46 kWh) | 8.000 W |
| Farm, warehouse, small business | 40 – 70 kWh | 9 – 15 (46 – 77 kWh) | 8.000 W |
Daily consumption figures are typical reference values for Spanish homes, not catalog figures Genergy: The actual sizing depends on your equipment, the location, and the number of days of autonomy you want without sunlight. We'll calculate it for you using the contact form.

Why Choose an Off-Grid Solar Kit? Genergy
Grows with you
From 5 to 77 kWh by stacking identical batteries, without changing the inverter or buying a new enclosure. A pre-packaged kit forces you to get the size right the first time; this one doesn't.
LiFePO4 with 4,000 cycles
More than 80% capacity after 4,000 cycles: one cycle a day equals eleven years. Compared to lead-acid batteries, they last four or five times longer.
The backup generator, from the same manufacturer
The inverter tolerates harmonics from a conventional generator or inverter and starts only one generator Genergy in SOL mode when the battery runs low.
Installation Without Surprises
Wiring and connection diagram included; batteries are stacked with the cables hidden behind them. The inverter equalizes the batteries based on their type and extends their lifespan.
Control via Mobile Phone
Standard WiFi: production, upload, and usage within the app, and remote access for technical support if diagnostics are needed.
SAT and Replacement Parts in Spain
An insulated kit is a twenty-year investment. Spanish brand, manufacturer, technical support, and genuine parts: when something goes wrong, it matters who’s there to help.
How to Size an Off-Grid Solar Kit in Three Steps
It's the calculation that almost no one shares—and the one that keeps you from having your power shut off in January. With a piece of paper and your old electricity bill (or a list of your appliances), you can do it in ten minutes.
Typical reference consumption figures, not catalog prices Genergy. Every installation is different: if you send us your list of appliances and their locations, we'll send you the sizing information via the contact form.
What an insulated kit needs to last twenty years
Lithium LiFePO4, lead-free
The lead-acid batteries still sold in this price range last for 500–1,200 cycles and cannot handle deep discharges. The LiFePO4 batteries in this kit last for 4,000 cycles at 80% capacity. The difference is whether you have to replace the batteries two or three times—or not at all.
Hybrid inverter, not just a charger
A hybrid system manages the panels, battery, grid (if available), and generator all at once, and prioritizes solar power. A simple inverter-charger cannot communicate with either the generator or the grid.
Generator Input
In a typical, isolated home, sooner or later there will be a week without sunshine. The fact that the inverter can handle a generator and start it up on its own isn't a bonus—it's what keeps you from being left in the dark.
Expandable without changing anything
Adding a battery shouldn't require replacing the inverter, cabinet, or wiring. With this kit, adding another battery is as simple as stacking it on top and connecting it.
Wide-range MPPT
The 140- to 430-volt input supports panels of different power ratings and series, both now and when you replace one in ten years.
Who is responsible?
Batteries and an inverter from a manufacturer that offers technical support in your country and remote access to the equipment. An off-grid kit from an unknown brand is cheap—until the first failure.
