When you place your order, we’ll notify the installer. They will then contact you to agree on a date for an inspection of your property as well as the installation date.

You can expect to be contacted by our installer within 3 business days from receipt of the order confirmation.

The meter is a 3-phase consumption and solar production meter. It is used to control when the battery charges and discharges.

If, for example, the solar panels produce more energy than the house uses, the battery will automatically store the surplus solar production. If, however, the meter shows that consumption exceeds production, the battery can cover the excess use with stored energy.

The energy meter will be delivered as three parts:
1 MODBUS energy analyzer
2 x 3-phased current transformers (60amp)

Environmental Surcharge

The environmental surcharge covers the cost of recycling the battery when it no longer functions.

Peace-of-Mind Agreement

10 years’ peace of mind
When you buy a solar cell battery from XOLTA, you can extend your peace of mind by 8 years with a 10-year Peace-of-Mind Agreement.

This 10-year agreement includes:

Mandatory 2-year warranty period

Onsite support: Visit and repair by an authorized installer at your home in the unlikely event the battery does not work optimally

Automatic software updates: You always have a full overview of your battery’s performance in terms of savings, CO2 and purchasing power from the grid

Prepared for changes in net tarriffs: Soon, your XOLTA solar cell battery will be able to use your stored electricity when it makes most sense in relation to future tariff increases

Hotline: Call us at +45 7060 2017 from 9 a.m.-4 p.m. on weekdays if you have problems with your battery

24/7/365 monitoring: Every day, around-the-clock, we monitor your battery to ensure optimal and safe functioning

During the 10-years of the Peace-of-Mind Agreement, you get expert support for your solar cell battery at no extra cost. XOLTA works only with authorized electricians who know our advanced products inside and out. No matter what happens to your battery, you will incur no additional charges during the agreement period.

Furthermore, you are assured that your solar cell battery is always up to date. Every day, we’re working to increase the economic benefits of XOLTA’s solar cell batteries.

XOLTA’s Peace-of-Mind Agreement is one of the best on the market. You pay only 495kr/year for the BAT-5 and 595kr/year for the BAT-10, and you’re covered from day 1. You are invoiced annually – initially, when you buy your battery and thereafter at the end of a year passed in the agreement. You cannot enter the agreement at a later point in time; it has to be done at time of purchase of the battery. You can always discontinue the agreement with one month’s notice after the end of the current month. In that case you will be reimbursed for months already paid.

If you do not want XOLTA’s Peace-of-Mind Agreement, you are of course covered by the 2-year, mandatory warranty period. Should you need support from an installer/electrician after this period, it will be invoiced at 750kr/hour + 3.5kr/km for driving. Islands must be connected to the mainland by a bridge.
