When designing an off grid solar system, one of the most important decisions is choosing the right battery storage. A solar battery is the heart of any stand alone power system, storing energy from your panels and keeping your home or business running when the sun is not shining.
For Australians looking for a robust and cost effective option, the ZYC SIMPO 5000 has become a competitive alternative to more established brands like BYD and PowerPlus. At Stand Alone Power Systems, we specialise in designing and installing customised off grid solar and battery solutions across Queensland, and we have taken a close look at what the SIMPO 5000 offers.
What is the ZYC SIMPO 5000
The ZYC SIMPO 5000 is a 48V lithium ion battery module with 5.12 kWh capacity, designed for residential and small commercial off grid systems. Manufactured with LiFePO4 lithium iron phosphate chemistry, the SIMPO 5000 balances energy density with safety and durability.
Key features
- 5.12 kWh per module
- 48V nominal voltage
- Scalable system with multiple units paralleled for larger off grid installations
- 10 year warranty subject to conditions
- Cycle life approx 6,000 cycles at 80 percent depth of discharge DOD
- Compact design for easy wall or rack mounting
This makes the SIMPO 5000 suitable for a wide range of off grid solar applications, from small cabins and tiny homes to full scale stand alone power systems.
Why battery choice matters in off grid solar
In grid connected solar systems, excess power is fed back into the grid. In off grid setups, batteries are the only way to store solar energy for use at night or during cloudy weather. Choosing a durable and efficient off grid battery ensures
- Reliable power supply even during long periods without sun
- Reduced reliance on backup generators saving on fuel and maintenance costs
- Long term cost savings thanks to higher cycle life
- Flexibility to scale your system as your energy needs grow
The ZYC SIMPO 5000 ticks many of these boxes, making it an appealing option for homeowners and businesses in regional and rural Queensland who want energy independence.
Comparing ZYC SIMPO 5000 with other off grid batteries
Many customers compare between ZYC, BYD, and PowerPlus. The SIMPO 5000 positions itself as a mid range, cost effective option, providing flexibility and solid performance. It is not as premium priced as Australian made PowerPlus, but still carries comparable specifications to BYD.
Advantages of the ZYC SIMPO 5000 for stand alone power
- Expandable storage multiple modules can be connected in parallel, giving homeowners the flexibility to expand as their power needs grow.
- Long life cycle with approx 6,000 cycles at 80 percent DOD, users can expect reliable performance for more than 10 years.
- Cost effective generally priced lower than Australian made brands, making it a popular choice for budget conscious off grid solar projects.
- Compact and lightweight easier to install in smaller homes, sheds, or cabins.
- 10 year warranty peace of mind for long term off grid living.
Applications in off grid solar systems
| Feature | ZYC SIMPO 5000 | BYD LV Flex | PowerPlus eco4840P |
|---|---|---|---|
| Capacity per module | 5.12 kWh | 5.0 kWh | 4.8 kWh |
| Chemistry | LiFePO4 | LiFePO4 | LiFePO4 |
| Cycle life | approx 6,000 cycles | approx 6,000 cycles | approx 6,000 cycles |
| Warranty | 10 years | 10 years with restrictions | 10 years |
| Scalability | Yes | Limited by 50 kWh residential | Unlimited |
| Country of assembly | China | China | Australia |
- Residential off grid homes primary power source for households disconnected from the grid.
- Rural properties farms, sheds, and workshops needing reliable power.
- Remote cabins or weekenders smaller systems that require dependable backup storage.
- Commercial off grid sites mining, agriculture, and telecommunications where power reliability is critical.
In each of these scenarios, pairing the SIMPO 5000 with a high quality inverter or charger such as Victron, Selectronic, or SMA creates a complete solution.
Local support and considerations
While the ZYC SIMPO 5000 provides competitive specifications, one consideration is local support. Unlike Australian made PowerPlus, ZYC batteries are imported. That means warranty claims and technical support depend on the distributor.
At Stand Alone Power Systems, we only install products with proven Australian distributor backing and strong after sales support. This ensures our customers in Queensland are not left without help if an issue arises.
FAQs about off grid batteries and ZYC SIMPO 5000
How many ZYC SIMPO 5000 batteries do I need for my home
That depends on your daily energy use. A typical off grid home may need anywhere from 20 to 100 kWh of usable storage, which equals 4 to 20 SIMPO 5000 modules.
Is the ZYC SIMPO 5000 better than BYD or PowerPlus
Each has strengths. ZYC is affordable and solid, BYD has strong brand recognition, and PowerPlus is Australian made with unlimited scalability.
How long will the ZYC SIMPO 5000 last
With approx 6,000 cycles, you can expect around 10 to 15 years of use, depending on depth of discharge and environment. At the end of the warranted 6,000 cycle life they still have a capacity of 70 percent.
Can I add more batteries later
Yes, the SIMPO 5000 is modular, so you can start small and expand as needed.
