Do I need to upgrade my solar system?
It depends on your current system and your energy needs. If your current system is not meeting your energy needs or you want to maximize your energy savings, then an upgrade may be necessary.
Can I add storage batteries to my solar?
Yes, you can add storage batteries to your solar system. Storage batteries can help you store excess energy generated during the day for use during peak demand periods or even throughout the night. It can also reduce your reliance on the grid and help you save money on energy costs.
Should I keep the old system or choose the new one?
It depends on your current system and your energy needs. If your current system is not meeting your energy needs.
For example, you have a 3.5kW system with a 5kW inverter, and you’d like to upgrade 5kW system and 5kW battery with your old inverter.
In this case, you have three options to choose.
1, Adding panels up to 5kW, but you have to think about you may not be able to buy exactly the same type of solar panels. Using two different model of solar panels on the same system may cause compatibility issues, such as mismatched performance, that can result in an inefficient and unreliable solar system. You should ensure your inverter has multiple MPPTs, which means you can connect two different model panel in two seperate MPPT, however, it just reduce the risk of compatibility issues instead of eliminating the problem completely. So, this option is not good for you.
2, Keeping old whole system and installing a complete new system. Thus, you have two solar systems. If you are after a solar battery, just replace the old inverter with a Growatt SPH 5000 inverter because SPH has AC coupled function, it can help you connect the two system and charge power to your solar battery.
3. Removing all old system items including panels and inverter, choosing a newest system. 6.52kW + 5kW hybrid inverter + 5.12kWh solar battery. Yes, it’s most flexible solution. Although the cost will be a little higher than the previous two options, but you get the best plan.
