Your ideal battery

AC Batteries

Buying guides:
We’ve compiled buying guides for these leading brands: Tesla, Franklin WH (coming), and Alpha ESS. Sigenergy is also available as an AC-coupled battery, and due to its primary topography, the Sigenstor system is available in our DC-coupled battery section (further below).
1) You have an existing solar energy system, or
2) Your are looking for an elite level home energy ecosystem as part of a new design with solar panels.
Supply chain and the global competitiveness lithium cell technology affects a relative energy density value among all options. However, feature sets, brand bankability, broader ecosystems and software capabilities more often differentiate product options and price.
AC-coupled batteries offer more expansive features that may improve overall value ahead of comparing energy density/cost-per-kWh, alone.
Always be aware a systems feature set vs your expectations when comparing AC and DC coupled batteries.
DC Batteries
Perth Solar Warehouse provides six leading DC-coupled batteries ideal for popular hybrid solar inverter brands connected to the Western Power/Synergy energy network.
Reviews:
We’ve generated in-depth buying guides for all leading DC-Coupled battery brands: Sigenergy, Sungrow, BYD, Goodwe, Growatt, and iStore.
You have an existing solar energy system with a compatible hybrid inverter that you would like to add simplified storage capacity to.
OR, you are installing a new solar energy system and want to increase solar capacity above STC and grid limitations [Note: selected AC-coupled batteries are now also approved achieve a similar oversizing loophole].
The most significant appeal of DC-coupled batteries is the cost-per-kWh when increasing energy density. This improved storage affordability comes at the expense of reduced features.
Due to the scaled back nature, DC coupled solar batteries by Perth Solar Warehouse provide the best value cost-per-kWh for energy storage. However, this is often balanced out when considering additional hardware in hybrid inverter costs and blackout protection features if required.
