Grid-Tied Inverter (add Solar Panels Only)
Grid-tied inverters are designed to work in conjunction with the utility grid. They convert the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity that can be fed into the grid or for self-consumption.
Inverter Charger (add Batteries Only)
An inverter charger performs the dual function of converting DC electricity from batteries into AC electricity for use in appliances and devices, and charging the batteries from an AC power source when available. Inverter chargers are commonly used in off-grid or hybrid systems where battery storage is essential.
Solar panels can be added to an inverter charger system by using a (MPPT) Maximum Power Point Tracking (DC Coupled) or a Grid-Tied inverter (AC Coupled).
Hybrid Inverter (add Solar Panels and Batteries)
A hybrid inverter combines the functionality of both a grid-tied and inverter charger. It allows you to use energy from solar panels, batteries, and the grid, offering flexibility and reliability. Hybrid inverters are ideal for areas with intermittent grid power or for maximizing self-consumption of solar energy.
Off-Grid Inverter
Off-grid inverters are used in standalone solar power systems where there is no access to the utility grid. They convert DC electricity from solar panels into AC electricity for use in appliances and devices. Off-grid inverters are often paired with battery storage systems to ensure continuous power supply, making them suitable for remote locations or areas with unreliable grid access.

System Sizing Guidelines
To appropriately size a solar panel system, battery backup, and inverter for residential or commercial applications, several factors must be considered. Please be aware that the figures provided below are estimations and are not exact, as they do not account for all variables.
Determining Solar Panel Size:
Start by assessing the average monthly electricity expenditure. For instance, an average household spending R1500 monthly, with a grid tariff of R3.00 per kWh, implies a consumption of 500kWh per month. This translates to an average daily consumption of 16.6kWh (500/30).
To generate 16.6kWh of electricity daily from solar panels, considering an average sunlight duration of 5.5 hours, a 3.03kWp solar array is required (16.6 / 5.5). This typically necessitates around 6 x 500W solar panels.
Selecting Inverter Capacity:
If the solar array exceeds 3kWp, it’s advisable to opt for a 3kVA to 5kVA inverter to manage the power efficiently. A 3kVA inverter is usually adequate if heavy loads like irons, kettles, microwaves, or other heating devices are not extensively used. However, to accommodate future growth, selecting an inverter slightly larger than current needs is recommended.
The max power used at any given moment also influences the inverter size. This can be determined by summing up the wattage of all the devices intended for backup during power outages. It’s crucial that the inverter size surpasses this total wattage figure. Device wattages are typically provided on their labels, facilitating accurate calculations.
Determining Battery Size:
Battery capacity hinges on uptime requirements. For a fully self-sustaining system, matching the daily consumption of 16kWh necessitates a 16kWh battery bank. However, for most households, half this capacity suffices to navigate through load shedding and cover nighttime consumption. In regions prone to adverse weather conditions or for off-grid setups, a larger battery bank spanning two days of supply is recommended.
Calculating battery backup time involves multiplying the total power required from the loads (total wattage) by the desired backup duration. For instance, if a 1kW load is anticipated to run for 4 hours during an outage, a battery bank exceeding 4kWh capacity is necessary to sustain it. Additionally, factors such as depth of discharge and the battery type (lead acid, gel, Lithium) introduce variations in parameters and lifespan, warranting careful consideration.
Recommended Sizing:
Inverter Size: 3kVA to 5kVA
Number of Solar Panels: 4 to 8
Battery Size:
– 5kWh to manage through load shedding
– 10kWh to handle load shedding and nighttime consumption
– 15 to 20kWh for complete self-sustainability
Considering Power Usage Patterns:
For households, where 40% of power is typically consumed during the daytime and 60% at night, prioritizing battery backup over solar panel capacity is advisable.
In contrast, companies often utilize 80% of their power during the daytime and only 20% at night. Hence, emphasizing more on solar panel capacity and less on battery backup is prudent for commercial setups.
By aligning system sizing with consumption patterns and considering future requirements, one can design an efficient and resilient solar power system tailored to specific needs.
Recommended System Size based on Monthly Electricity spend :
1.6kW R 300 – R 800
3kW R 800 – R 1 500
5kW R 1 000 – R 2 000
6kW R 1 500 – R 3 000
8kW R 2 000 – R 4 000
10kW R 4 000 – R 6 000
15kW R 6 000 – R 8 000
24kW R 8 000 – R 12 000
30kW R 12 000 – R 16 000
45kW R 16 000 – R 21 000
