Three diagrams with photovoltaics and energy storage – Hybrid, Off Grid, Grid-Tied with Batteries.

In this article, you will find the three most common solar PV power systems for domestic and commercial use. For simplicity we draw a single phase system but the concept is applicable for three phase system with one (3-phase) or multiple inverters in parallel.   Diagram A: Hybrid Photovoltaic […]

Which Electric Vehicles Are Compatible with Bidirectional Quasar Charger

Yes the Nissan Leaf is one for the few vehicles capable of bi-directional charging. Below is some information on the current capabilities of the Quasar. Quasar’s main applications can be divided into V2G (Vehicle-to-Grid) and V2H (Vehicle-to-Home), depending on the user/company needs and services that want to be provided to […]

charging time for batteries from solar chargers

How long does it take to charge batteries from solar panels

Using simple mathematical formulas, we set up a simple guide that will help you to calculate the charging time of your batteries using solar panels. In our example we consider the efficiency of an battery charger with MPPT controller which is more efficient compared to PWM chargers. If you […]

How to select the right 5kW MPPT off grid solar inverter 48V/230VAC. A simple guide

For large off-grid solar photovoltaic systems, the 48V battery-based system is the right solution because the current rating for the same power is reduced and smaller cables are required. 12V and 24V find more use in small systems up to 3000Watt.   Voltacon’s range of inverters consists of 5 […]

UK Grid Certification has changed to EREC G98 and G99.

Introduction The new standards occur from 27th of April 2019 and called Engineering Recommendation (EREC) G98 and G99. After that day any generators connected to UK distribution will have to comply. These two regulations, published by the Energy Networks Association (ENA), replace the G83/2 and G59/3 respectively. These new standards are applicable for all new solar, wind, battery storage, CHP […]

How to monitor hybrid solar inverters over the internet

Introduction A reliable connection directly to your photovoltaic system is more crucial than ever before. The daily production, pontial error, faults or warning should be quickly reported back to the user no matter how he is from his solar installation. To reduce the pontial down-time of the solar inverter, […]
