Selectronic SP PRO - Hybrid off-grid Inverter Review
Selectronic manufacture the SP PRO which is possibly the most advanced battery inverter/charger available and designed to be used for a huge range of hybrid on-grid or off-grid solar and energy storage systems.
Off-grid and Hybrid Multi-mode inverters explained
We review the leading multi-mode inverter-chargers that are capable of operating in on-grid (hybrid) or off-grid modes and can be used to create both AC and DC coupled solar systems. These modern powerful inverters are often used to build large energy storage and backup power systems for both residential and commercial applications.
How to choose a quality solar panel
The best quality solar panels from leading manufacturers LG energy, SunPower, Trina, REC and Winaico with the highest performance, efficiency, warranties and reliability.
Best 60A+ MPPT Solar Charge Controllers
We review the best quality and highest performing MPPT solar charge controllers used for professional off-grid solar installations. from the worlds leading MPPT manufacturers including Victron, AERL, Outback Power, Morningstar, Midnite solar and Schneider Electric.
Solar, battery and hybrid inverters explained
There are many different types of inverters now available including solar inverters, off-grid inverters and hybrid inverters. In this article, we explain what the different inverters are used for and the various functions. Plus we explain some of the conflicting and confusing terminologies such as battery-ready and inverter-chargers.
Lead-acid Vs lithium-ion batteries
Despite the higher cost, lithium-ion batteries have surged in popularity and have become the preferred option for solar and home energy storage systems. We compare the leading lithium batteries from Simpliphi and Pylontech against the advanced deep-cycle lead-acid batteries from Narada and BAE.
Solar systems explained - On-grid, Off-grid & Hybrid
Introduction to the main types of solar power systems: on-grid, off-grid, and hybrid with battery storage. We explain the main components of a solar system and describe what type of inverter, batteries and other equipment is required for each type of system.
How heat pumps work
A heat pump is a device that moves thermal energy (“heat”) from one area to another.
Deep cycle batteries - Flooded, AGM, Gel & Lead carbon
Introduction into lead-acid deep cycle batteries, how they work, their benefits and limitations.
Battery Review - Energy storage systems
Most home battery storage systems are made up of lithium based battery modules housed within a unit containing a charger and battery management system (BMS).
Off-grid solar dairy farm - Project review
Dairy farms use a lot of energy to operate due to the high power requirements of vacuum pumps, compressors, milk vat refrigeration systems, and irrigation in summer. To add to the difficulties, over a third of the energy used is early morning before the sun. With this in mind, powering a dairy farm using a solar off-grid battery system posed many challenges.
