Omnicharge Solar OCS — MPPT solar charge controller 20–70 A
Country: Netherlands · Model: Omnicharge Solar OCS
The Omnicharge Solar OCS MPPT charge controller accepts up to 100, 150 or 250 V from solar panels and charges the battery at 20–70 A, which corresponds to an array from 260 Wp to 3.68 kWp. It is used in off-grid photovoltaic systems where the solar plant runs on a battery without a grid connection.

Description
The OCS 100 version works with 12 or 24 V batteries, while the OCS 150 and OCS 250 support systems from 12 to 48 V. The number in the name corresponds to the maximum array voltage, so the OCS 250 accepts longer series strings of panels with lower currents in the cables from the roof. Conversion efficiency is 98 % and maximum power point tracking accuracy is 99 %, so only a negligible share of the panel energy is lost as heat. Cooling is natural, without fans, so the case has no wearing parts and the controller makes no noise in a living compartment. The operating temperature of −35…+60 °C suits unheated technical rooms. Charging parameters are set through the Dashboard Mobile app on a smartphone.
How to choose
The model is determined first of all by the open-circuit voltage of the panel string on the coldest day, which must stay below 100, 150 or 250 V respectively. Then choose a current of 20–70 A to match the array power and battery voltage, because the same current at 48 V carries four times more energy than at 12 V. For a 48 V bank only the OCS 150 and OCS 250 are suitable, while the OCS 100 is limited to 12/24 V systems.

FAQ
How much solar panel power can be connected to the Omnicharge Solar OCS?
From 260 Wp to 3.68 kWp depending on the model and battery voltage. The upper limit is reached on the larger models with a 48 V battery.
Is the OCS 100 suitable for a 48 V battery?
No, the OCS 100 is designed for 12 and 24 V systems. For 48 V you need the OCS 150 or OCS 250.
Does the OCS controller need forced ventilation?
No, cooling is natural and there are no fans; it is enough to leave free space around the case. The operating range is −35…+60 °C.
What is the efficiency of the Omnicharge Solar MPPT controller?
Conversion efficiency is 98 % and maximum power point tracking efficiency is 99 %. Charging settings are changed through the Dashboard Mobile app.
