PV equipment

About this category

PV equipment

This category holds the equipment solar PV systems are built from: solar panels, inverters, smart meters, solar cable, MC4 connectors and DC protection. It also holds the complete PV + ESS packages — 6 to 30 kW of PV with a 5 to 60 kWh battery, each a whole system with supply, installation, metering and commissioning.

The solar panels (PV modules or photovoltaic panels — for electricity they are the same thing) come from JA Solar, Canadian Solar, Suntech, Trina Solar, Jinko, AE Solar, DAH Solar, Tongwei, Hanover and Shinefar: monocrystalline and bifacial modules with N-type and P-type cells. The inverters are Deye hybrid inverters — single-phase and three-phase, for a low-voltage (LV) or high-voltage (HV) battery — and a Growatt off-grid inverter for sites with no grid connection. For metering and monitoring there is the Deye DTSU666 smart meter, a Deye smart CT and the Deye smart transmitter.

The size of a PV system is set by what the site consumes, not by the area of the roof: we start from the electricity bills or the load profile, the capacity granted by the grid operator and the operating mode wanted. That is why the catalogue shows no prices — a quote follows the enquiry, once we have seen the site’s data. Power Design Engineering designs, supplies and builds solar systems for homes and businesses in Kardzhali, Momchilgrad and across Bulgaria: rooftop and ground-mounted PV systems, with a battery or without.
