Installer Guides

LV and HV classes in batteries Growatt are not interchangeable, and the choice is dictated by the inverter. Comparison of voltages, models, expansion limits, and controllers BMS — with a decision table.

Which module BMS to which inverter-battery pair: compatibility table for SPH, MIN, MOD and MID, models with BMS built-in and five pairing errors that most often end up returning to the construction site.

Guide to expanding an existing installation Growatt for energy storage: model verification by plate, shopping list for battery-ready units, capacity range and fair scenario for inverters without battery track.

How the emergency exit works in inverters WIT-HU, how much power does it actually give, which house circuits are worth connecting to it and what to remember when connecting N-PE.

Inverter installation procedure WIT-HU from site conditions, through drilling and tightening torques, to the sequence of electrical connections and verification after commissioning.

Dry contact in inverters off-grid Growatt allows you to automatically activate a generator or alarm depending on the battery status. We explain the NC/C/NO logic and configuration using an example. SPF6000ES PLUS.
