How we select

Backup starts with a list of loads.

First: what has to run during an outage, and for how many hours. That sets the inverter power (the sum of the loads with a 25 % margin, plus the start of the largest motor) and the battery capacity in watt-hours. Only then are the system voltage, the battery type and, if needed, solar panels or a generator chosen.

For an office, a shop, a boiler room or a home we size the system and select the inverter, batteries, cable and DC-side protection.

  • Pure sine wave for boilers, fridges and pumps
  • LiFePO4 for daily cycling: a service life of 3,000–6,000 cycles
  • 48 V for systems from 3–5 kW: lower current and thinner cable

Calculation

How much inverter and battery you need

Switch on what has to keep running during an outage and say for how many hours. You get the inverter power and the battery capacity.

We size the inverter with a 25 % margin over the total load and check it against the starting currents of the fridge and pumps. Capacity assumes 90 % inverter efficiency and a working depth of discharge of about 90 % for LiFePO4 and 50 % for gel and AGM batteries.

Questions and answers

How many kilowatts of inverter does a flat need?
Add up the power of everything that has to run at once, add a 25 % margin and check the starting currents: a fridge and a pump draw about three times more at start-up. Router, lighting, laptop and boiler come to about 300 W; with a fridge and a PC it is closer to 1 kW once start-up is counted. The calculator above does this automatically.
LiFePO4 or a gel battery?
LiFePO4 delivers about 90 % of its capacity and withstands thousands of cycles; gel and AGM give about 50 % working depth of discharge and a shorter life, but cost less up front. For daily outages take LiFePO4; for an occasional reserve gel is acceptable. All kits in the catalogue come with LiFePO4.
Can you select a system for an office or a production site?
Yes. Send the list of loads, the required autonomy and the supply details (phases, power) — we select the inverter, batteries and generator to specification, including items not in the online catalogue, and propose technically comparable equivalents by lead time and budget.
How do you deliver batteries, power stations and generators?
Kits, power stations and generators are bulky freight: we ship by Nova Poshta freight terminal or direct to site, items in stock within 1–2 working days. Timing and cost are confirmed in the quotation; for companies — an invoice and regular supplies.
