Low-voltage (48V) or high-voltage battery? 5 questions
Five quick questions about your building, your grid connection and your plans, and we'll tell you which battery family fits best. It takes about a minute.
Your result
A 48V low-voltage battery suits you
For your system a 48V battery is the simplest choice and the cheapest per kWh: modules connected in parallel, no minimum number, and you can add more later as long as you stay with the same model. Pair it with a 48V hybrid inverter or inverter/charger, and check that the battery is on the inverter's compatibility list.

Your result
A high-voltage battery suits you
With your power and storage needs, high voltage works best: modules in series, lower currents, thinner cables and better efficiency at high power. You'll need an HV hybrid inverter, a control box for each tower and at least the minimum number of modules the inverter requires; plan any expansion in modules of the same model.

Both options work for you
Your answers sit in the middle, where 48V and high voltage both make sense. 48V costs less to start and is easier to expand a little at a time; high voltage is more efficient with three-phase inverters and larger batteries.
