Sparky Amrit Thapa
Project Manager & A Grade Electrician
After doing sub-contracting with many Solar Retailers company, Sparky Amrit decided to get in-house Solar Retailer business so that existing or new customer can get directly benefits from our designed and installed system. Likewise, other solar retailers bluff many things which are not practical in a real circumstance. Do not fall into less out of pocket money, think about what sort of solar panel and inverter brand, quality of solar installation materials used, installation of workmanship, detail discussion about location of solar panels and inverter with battery storage system in your house, electrical contractor and installer experience matters while doing design and installation of solar pv system with battery storage. For example, if you do not know full function of solar with battery storage system when installer install it without automatic backup into your house. In this case, your house do not have backup or emergency power supply when there is black out or grid outage. Getting quick solar and battery quotes from many solar retailers company does not satisfy what you are actually looking for. Thorough depth knowledge of experience required to do battery installation with backup configuration into your house.
Doing compliant backup requires your Main switchboard/Sub-board upgrades. Installer must connect backup circuits when installer install the battery storage system. Keeping backup system ready for future proof power in your house is one of the smartest ways to invest in solar and battery system. None of the Solar Retailers are aware of backup circuits configuration. Many times, solar retailers agreed on whatever technical challenges which were not possible on the day of installation. Beware of those kind commitment from solar retailers. This is why solar retailers’ business must be run by in-house licensed electrician with accredited designer and installer. If solar retailers are sneaky then some times installer might be sneaky on his/her workmanship quality.
