Selection and comparisons

Second generation of the magazine APX changed the shopping list: no more separate module BMS and cascade cables. What exactly has changed, how many modules to choose and for which inverters? Growattand that fits.

Comparison of three hybrid families Growatt up to 15 kW: phases, powers, number of trackers MPPT, compatible ARK batteries/APX and three different backup power architectures - with selection table and scenarios.

Series parameters WIT 17-25K-HU and practical selection criteria for a house with a heat pump and car charger, including limitations on the connection side.

Capacity selection methodology instead of advertising round numbers: evening-night balance, peak power of modular configurations, reserve for emergency power supply and a fair bill for homes with a heat pump.

Oversizing limits straight from the MOD series manual, MID i MIN instead of forum percentages: Recommended table MaxPV power, hard voltage and current limits, winter Voc procedure, and three numerical examples.

System construction APX: modules 5 kWh, power module per inverter line, configurations 5-30 kWhPower-capacity table, ordering pitfalls (power module, EU version) and selection for home profile.

What is the difference between HV and LV architecture, how does it translate into currents and conductors, and which family of inverters Growatt works with which battery — with a decision table.
