Giter batteries are low cost and manufactured in China. They are compatible with small inverters that have a low run time. Giter’s medium battery has a charge/discharge power of 2500 W and is compatible with 48V Kodak and Sunsynk inverters, the lithium-ion battery is also parallelable up to 6 batteries for a total of 30.24kWh


A dedicated BESS (battery energy storage system) manufacturer, Pylontech consolidates expertise in electrochemistry power electronics and system integration. The 4.8kWh lithium-ion battery has a parallel capability of up to 16 units and a usable capacity of 4560Wh. A unique feature of Pylontech is its self designed Battery Management System (BMS) that protects the cell from abnormal temperature, current and voltage.


Huawei solar batteries have a high energy density and a prolonged lifespan. Designed to seamlessly integrate with Huawei inverters, they are low-cost, have a five-year warranty and maximise energy utilisation.

The solar battery is engineered for versatility and caters to diverse energy storage requirements.

Although a well-rounded solar battery, the downside of the Huawei solar battery is that it is not interchangeable with other brands.

Battle of the Batteries: Lithium-ion vs Lead Acid


In a solar energy system, an inverter plays a crucial role. Ensuring the efficient utilisation of solar-generated energy, the inverter acts as the bridge between solar panels and electrical appliances. The inverter and solar battery work as a seamless unit. The solar battery is a storage reservoir for excess energy produced by the solar panels during peak sunlight hours and instead of letting this surplus energy go unused, the inverter works in tandem with the solar battery to manage the flow of electricity.


There are two main types of inverters:

Sine wave – generally more expensive, they provide a stable power output that is best suited to sensitive appliances. Sine wave inverters also produce a cleaner power supply.

Modified sine wave – more affordable, but they have a distorted output supply.

Most inverters are equipped with additional features, such as a controller, and LCD display. These features make managing your power consumption easier. Depending on the type of solar battery backup system installed, you can add string inverter optimisers. Also known as a solar optimiser, the device is designed to enhance the performance of a solar photovoltaic (PV) system. String inverter systems connect a group of solar panels to a single inverter, which aggregates the power output, where electricity is converted from DC to AC electricity. We advise adding a solar optimiser to your home battery backup system if your roof is partially shaded or not oriented to catch sunlight at its best.


A Chinese distributor of complete photovoltaic power system solutions, Deye offers grid-connection and stand-alone grid as well as hybrid inverter systems, for small homes.


An internationally recognised inverter and battery storage brand, SunSynk provides off-grid and on-grid solutions. Their inverter battery components in the 5kW Sunsynk inverter with 5.5kWh AM-2 lithium-ion battery is ideal for larger homes. A ‘silent’ inverter, the SunSynck inverter is equipped with an easy-to-use interface with the addition of remote management, enabling you to track the performance of your inverter from your phone.
